In addition to providing color decoration for the coating, the function of pigment can also provide more improvements in physical and chemical properties for the coating, such as covering, light resistance, weather resistance, temperature resistance, chemical resistance, gloss, and mechanical strength.

Red Blue and Violet Organic Pigments for Coatings
Organic color pigment solutions can be used in coatings to provide a durable and attractive finish. There are a variety of organic pigment options available, including those based on azo, quinacridone, and perylene chemistries.

Azo pigments are some of the most commonly used pigments red in coatings. They offer good color strength, lightfastness, and durability, and can be used in a wide range of applications.

Quinacridone pigments offer excellent durability and lightfastness, and can produce bright, intense colors. They are often used in automotive coatings and other applications where long-term color retention is important.

Perylene pigments are known for their excellent lightfastness and heat stability, and are often used in high-performance coatings such as those used in the aerospace industry.

When using violet pigment solutions in coatings, it's important to choose a pigment that is compatible with the other components of the coating system, including the binder, solvents, and additives. The pigment dispersion process is also critical for ensuring the pigment is well-distributed and properly dispersed in the coating formulation.

Ultimately, the choice of blue color pigment will depend on the specific requirements of the coating application, including the desired color, durability, and other performance characteristics.

The Application of Organic Pigments in the Industry(2023年03月19日)

shanhucolor — 2023-03-13T12:46:31+0900

https://www.shanhucolor.com/products/pigment-red-169-cas-12237-63-7.html

Organic pigments are mainly used in the fields of plastics, inks, and coatings, of which the coating industry accounts for about 35%, with an annual consumption growth rate of about 2.5% and a sales growth rate of 3%. Although the share of organic pigments in coatings is less than that of inorganic pigments, with the continuous progress of coating technology and the needs of the development direction of coatings, as well as the characteristics of organic pigments themselves, organic pigments are more and more widely used in coatings.

The organic pigment varieties used in coatings are monoazo yellow and monoazo orange pigments, disazo pigments, naphthol pigments, naphthol AS pigments, azo red pigment lakes, benzimidazolone pigments, disazo condensation Pigments, metal complex pigments, isoindolinone pigments and isoindoline pigments, phthalocyanine pigments, quinacridone pigments, perylene pigments, 10-H-pyrroloidine pigments, diketopyrrolopyrrole pigments , thioindigo pigments, heterocyclic anthraquinone pigments, anthraquinone pigments, hydroquinone pigments, polycarbocyclic anthraquinone pigments, dioxazine pigments and quinophthalone pigments, among which phthalocyanine pigments are the most important.

1. Application of organic pigments in architectural coatings

Because latex paint is rich in color, can be chosen at will, with good decorative effect and long service life, architectural coatings with acrylic emulsion as film-forming material play an increasingly important role in urban decoration.

As an important component of latex paint, the selection and use of organic pigments directly affect the color retention of latex paints, and the understanding of pigment properties and applications can guide the production of high-quality latex paints. Organic pigments will not be affected by physical and chemical factors during use, generally insoluble in the medium used, and always exist in the original crystal state. The coloration of organic pigments is achieved by selectively absorbing and scattering light.

2. Application of organic pigments in automotive coatings

In the coatings industry, the technical content of automotive coatings is high and the construction is difficult. It can be said that the level of a country's automotive coatings basically represents the overall level of the country's coatings industry, which provides a great deal for the resins and pigments used for supporting automotive coatings. High quality requirements.

Automotive coatings must meet the weather resistance, heat resistance, acid rain resistance, ultraviolet radiation resistance and hue migration resistance of metal surface coatings. Pigment for automotive coatings is a high-quality colorant. The change of automotive color is solved by the adjustment of organic pigments in coatings. Therefore, the application of organic pigments in automotive coatings must have light stability, chemical resistance, Anti-bleeding, thermal stability; for automotive topcoats, such as metallic glitter paints, organic pigments are required to have high transparency, which complements the hiding power of inorganic pigments.

3. Application of organic pigments in coil coatings

Coil coatings are classified into topcoat, primer and backcoat according to their functions. The main types of primers are epoxy, polyester and polyurethane; the main types of topcoat and backcoat are PVC plastic, polyester and polyurethane. type, acrylic type, fluorocarbon type and silicon-modified polyester type, etc.

In the process of color sheet production, 20-25kg of coil coating is consumed per ton of galvanized sheet, and the topcoat using pigments accounts for about 70% of the coating usage. Common colors are white gray, sea blue and crimson, among which white gray accounts for about 50%, sea blue accounts for about 30%, crimson accounts for about 10%, and other colors account for about 10%. Organic pigments in aquamarine and crimson account for about 3%-5% of coil coating usage.

As we all know, colorants are basically divided into organic pigments, dyes, and inorganic pigments. Organic pigments have developed rapidly recently. What are the similarities and differences with the other two colorants?

1. The similarities and differences between organic pigments and dyes

Both organic pigments and dyes are colored organic compounds. From the chemical structure of organic pigments and dyes, the two are very similar, and even some organic compounds can be used as both dyes and organic pigments, but organic pigments and dyes do Are two different concepts, the difference between them is mainly the application performance is different.

The traditional use of dyes is to dye textiles, while the traditional use of pigments is to color non-textiles such as inks, paints, coatings, plastics, rubber, etc. This is because dyes have affinity (or directness) to textiles and can be adsorbed and fixed by fiber molecules; while pigments have no affinity for all coloring objects, and mainly rely on resins, adhesives and other film-forming substances to combine with the coloring objects together.

In the process of use, dyes are generally first dissolved in the use medium. Even disperse dyes or vat dyes undergo a process of first dissolving in water from a crystal state to a molecular state and then dyeing on the fiber during dyeing. Therefore, the color of the dye itself does not represent its color on the fabric.

During the use process, the pigment always exists in the original crystal state because it is insoluble in the use medium. Therefore, the color of the pigment itself represents its color in the substrate. Because of this, the crystal state of the pigment is very important to the pigment, while the crystal state of the dye is not so important, or the crystal state of the dye itself is not closely related to its dyeing behavior.

Although pigments and dyes are different concepts, they can be used in common in certain situations. For example, some anthraquinone vat dyes, which are insoluble dyes, can also be used as pigments after pigmentation. Such dyes are called pigment dyes, or dye pigments.

2. The similarities and differences between organic pigments and inorganic pigments

Compared with inorganic pigments, organic pigments have many unique advantages. By changing the molecular structure of organic pigments, a wide variety of varieties can be prepared, and they have more vivid colors and brighter hues than inorganic pigments.

Organic pigments also have much higher tinting strength than inorganic pigments, and can be prepared into varieties with high tinting strength and high transparency to meet the requirements of high-grade coatings and printing inks. Most organic pigment varieties are less toxic, while most inorganic pigments contain heavy metals, such as chrome yellow, red red, vermilion, etc., which have certain toxicity.

Low-grade organic pigments are inferior to inorganic pigments in terms of light fastness, weather fastness, heat resistance and solvent resistance, but some high-grade organic pigments (such as quinacridone pigments, phthalocyanines, etc.) Pigments, etc.) have excellent light fastness, weather fastness, heat resistance and solvent resistance, and their acid/alkali resistance is also better than inorganic pigments, because some inorganic pigments have poor acid/alkali resistance. Such as: chrome yellow will turn black in the presence of hydrogen sulfide, red in the presence of alkali; ultramarine blue is easily decomposed by acid.

The variety, type, output and application range of organic pigments are constantly growing and expanding, and they have become an important class of fine chemical products.

As a professional pigment red factory, we provide pigment red 210, pigment red 269, pigment red 81:2, red pigment, etc. For more information about organic pigments examples, please feel free to contact us!

Influence of Organic Pigments on Coating Properties(2023年03月17日)

shanhucolor — 2023-03-13T12:45:08+0900

https://www.shanhucolor.com/products/pigment-red-268-cas-16403-84-2.html

1. The development of organic pigments

The proportion of organic pigments used in the coatings industry has been increasing, and currently accounts for about 26% of the color pigments used in coatings. In recent years, with the rapid development of the coatings industry, new coatings have been continuously developed, and the proportion of high-end coatings has increased significantly. The demand for pigments has grown rapidly, and its varieties and properties have put forward more and higher requirements, which provides a good opportunity for the development of the organic pigment industry.

2. The influence of the physical properties of organic pigments on the performance of coatings

The physical properties of organic pigments include density, specific surface area, particle size, crystal form, dispersibility and stability. The density of the organic pigment is 1.0-2.0g/cm3, and the specific surface area is 10-100m2/g; the ideal state of the organic pigment particle should be the primary particle, and its particle size is 0.01-0.05μm. However, due to the extremely high surface energy of such fine particles, strong agglomeration will occur to form aggregates (size of 0.05-0.4μm), and aggregates will still agglomerate to form aggregates (size of 0.1-20μm), so the usual organic pigments The particles are a mixture of aggregates and agglomerates.

The size of the organic pigment particles has a great influence on the color performance of the paint. On the one hand, it will affect the covering power and tinting power of the paint. Within a certain range, the particle size of the pigment increases, and the covering power of the paint increases; when the pigment particles become smaller, the specific surface increases and the tinting power of the paint increases. Pigment particle size also has an impact on the color of the paint. Usually, the particle size is large, the particle size distribution is wide, and the color is dark; on the contrary, the color is bright.

On the other hand, pigment particle size also affects the UV resistance of coatings. When the particles become smaller, the specific surface area increases, the absorbed light energy increases, and the degree of damage also increases, so the paint fades faster.

Pigments with small particle size and low gravity make the coating less prone to stratification and precipitation. However, pigments with small particle size have a large specific surface area and increase the surface energy, which increases the chance of flocculation and roughness of the coating, which is not conducive to grinding and dispersion.

Most organic pigments exist in a crystalline state, and the phenomenon of "isomorphism" is common. The common crystal forms of copper phthalocyanine are Q-type red light blue (such as Pigment Blue 15), which has poor stability. There are three crystal forms, α, β and γ. The α type has no application value, the β type is purple-red, and the γ type is blue-red. When designing the coating formulation, attention should be paid to the rational use of additives and solvents to prevent the transformation of different crystal forms under certain conditions, which will cause the color shift of the coating, and it is difficult to find the color according to the standard plate.

As one of the most professional organic pigment manufacturers, we provide pigment red 210, pigment red 268, red pigment powder, pigment coating, etc. For more information about examples of organic pigments, please feel free to contact us!

Physical Properties of Organic Pigments(2023年03月16日)

shanhucolor — 2023-03-13T12:44:22+0900

https://www.shanhucolor.com/products/pigment-red/

1. Organic pigment color

The color of the pigment is the most characteristic property of the pigment performance, especially the color of the coloring pigment and the color of the pigment is closely related to its chemical composition. A certain range of changes, although the chemical composition is the same, the crystal structure is not necessarily the same, the differences in particle size, particle size distribution, impurity content, etc. will cause differences in color and light, and color is extremely sensitive to these factors, and the human eye is extremely sensitive to color. Sensitivity, which is why it is difficult to control the absolute consistency of pigment shades.

The iron red produced by the same process has different colors due to different particle size and composition ratio, although the chemical composition is the same.

2. The hiding power of organic pigments

The pigment is added to the transparent base to make it opaque, and the minimum pigment required to completely cover the black and white grid of the base is the hiding power.

The optical nature of hiding power is caused by the difference between the refractive index of the pigment and its surrounding medium. When the refractive index of the pigment is equal to the refractive index of the binder, it is transparent, and it appears when the refractive index of the pigment is greater than that of the binder. The greater the difference between the two, the stronger the hiding power.

3. The tinting strength of organic pigments

The tinting strength is the result of the absorption and scattering of light by the pigment, which mainly depends on the absorption. The greater the absorption capacity, the higher the tinting strength. The chemical composition of different pigments, in general, the pigments of similar shades, the organic pigments are more colored than the inorganic pigments much stronger.

For pigments with the same chemical composition, the fluctuation of tinting strength depends on the size, shape, particle size distribution, crystal structure, and tinting strength of the pigment particles. It is also related to the dispersion of the pigment particles. The finer the dispersion, the stronger the tinting strength. Therefore, in order to improve the tinting strength, it is necessary to pay attention to the post-processing of the pigment, so that the tinting strength can be exerted better.

4. Organic pigment stability

The chemical composition of pigments is the main indicator of the difference between pigments. Pigments with different chemical compositions have different physical properties such as color, covering power, tinting strength, particle size, crystal structure, surface charge and polarity, and also determine the physical properties of pigments. The chemical properties of pigments vary.

Generally speaking, according to the nature and application of the pigment, the pigment is required to have a stable chemical composition and not be affected by the external environment. The chemical stability of the pigment will limit the use of some pigments. For example, lead-containing pigments can interact with H2S in the atmosphere. The reaction produces black lead sulfide, which makes the pigment dark and black, and sometimes its instability is used for some purpose. For example, pigments are basically insoluble in water, but for the purpose of anti-rust, anti-fouling or deliberately adding a certain medium to make them slightly water-soluble or the substrate to undergo a slight chemical reaction to protect the substrate.

5. Chemical resistance of organic pigments

The most essential nature of a pigment should be an inert substance, and it is difficult for a specific pigment to not react with any substance. At this time, it is required to make use of strengths and avoid weaknesses. The chemicals that the general coatings come into contact with are nothing more than acids, alkalis, salts, water, corrosive gases, organic solvents, etc. For example, iron yellow is more resistant to alkali and light than chrome yellow, so iron yellow can be used in architectural coatings.

6. Weather resistance, light resistance and heat resistance of organic pigments

The light resistance, weather resistance and heat resistance of pigments are the indicators of pigment performance in application, which directly affect their use value. Usually inorganic pigments pass through sunlight, and the action of the atmosphere will cause the color to darken and darken. In the same case, organic pigments are mostly faded.

In order to improve the light resistance, weather resistance, heat resistance and other properties of the pigment, for example: adding various chemical substances without changing the lattice structure, coating the surface of the pigment, passivating its surface, etc. Due to different treatment methods, different pigment varieties with unified chemical composition can be formed, which can be selected and used for different purposes.

As one of the most professional organic pigment manufacturers, we provide organic red pigment, the red pigment, pigment red, pigment coating, etc. For more information about organic pigments vs inorganic pigments, please feel free to contact us!

How to Accurately Classify Organic Pigments?(2023年03月15日)

shanhucolor — 2023-03-13T12:43:12+0900

https://www.shanhucolor.com/

Types of organic pigments belong to the colored compounds used in different fields. Colored substances can be divided into two categories: inorganic colored substances and organic colored substances. Except for a few natural compounds, they are all synthetic colored compounds. As a colorant for different purposes, it is often required to have high coloring strength, satisfactory vividness, and excellent durability (such as: heat resistance and acid/alkali stability, weather resistance color fastness, etc.).

There are many types of organic pigments, in order to facilitate application and understand their related chemical structures and properties, different classification of organic pigments methods can be used. It is usually classified according to different chromatography, molecular chemical structure and application performance.

1. Chromatographic classification of organic pigments

The natural organic pigments could be divided into yellow, orange spectrum; red, purple spectrum; blue, green, brown and black spectrum and so on.

2. Chemical structure classification of organic pigments

According to the color genes contained in the organic pigment molecules from pigment paste manufacturers, it is divided into six types of organic pigments: azo pigments, lake pigments, heterocyclic pigments, fused ring ketone pigments, phthalocyanine pigments, and other pigments.

3. Classification of organic pigment application performance and use

In the classification of use, it is divided into organic pigments for ink pigments, organic pigments for coatings, organic pigments for resin/plastics, organic pigments for rubber/latex, organic pigments for fabric printing and dyeing, and functional pigments, such as color filters for liquid crystal displays Use pigments, fluorescent pigments, electrostatic photocopying charges to produce pigments for layering, pigments for food and cosmetics, etc.

4. Application performance classification of organic pigments

In this classification, it is mainly divided into classic organic colour pigments and high-performance pigments.

Organic pigments are insoluble organic substances that are usually added to the substrate in a highly dispersed state to color the substrate. It is fundamentally different from dyes in that dyes are soluble in the dyeing medium used, whereas pigments are neither soluble in the medium in which they are used nor in the substrate being colored.

Many pigments and dyes have the same chemical structure, and they can be converted into each other by different methods of use. For example, some vat dyes and sulfur vat dyes can be used as fiber dyes if they are reduced to leuco; If not reduced, it can be used as a pigment for advanced ink.

Organic pigments are widely used in inks, paints, coatings, raw pulp coloring of synthetic fibers, pigment printing of fabrics, coloring of plastics, rubber, and leather, etc. Among them, the pigments of inks are used in the largest amount. The output of organic pigments accounts for about a quarter of the total output of dyes.

The Development of High-performance Coatings Requires Organic Pigments(2023年03月13日)

shanhucolor — 2023-03-13T12:39:11+0900

https://www.shanhucolor.com/products/pigment-blue/

Organic pigments are gradually developed with the advancement of organic dye technology, and form a relatively independent organic coloring material system with special properties, which is widely used in inks, coatings and plastics.

1. High-performance development of organic pigments

In recent years, the total output of the world's organic pigment industry has not grown much, but the output, varieties and specifications of high-performance organic pigments have increased significantly. Although the output of high-performance organic pigments does not account for a large proportion of the total output, due to the high performance and high added value brought by the high technology contained in the production of high-performance organic pigments, its output value exceeds that of mid-range organic pigments and accounts for half of the total output. The output value of low-grade organic pigments is comparable.

The main characteristics of high-performance organic pigments are macromolecular structure and complex chemical structure; the intermediate preparation process used is long, the synthesis process is complex, and the technical requirements are high; and a lot of money is spent on the treatment of "three wastes". Therefore, the research and development of high-performance organic pigments, Production has been monopolized in the hands of several European and American multinational companies with strong technical strength, and formed their company's brand products.

While developing new types of organic pigments, these internationally renowned organic pigment manufacturers are committed to studying the surface properties of pigments, endowing traditional pigments with ultra-high performance, improving product quality, and expanding application fields.

It will be the future development trend of organic pigments to continuously increase the varieties of high-performance organic pigments to meet the high-performance requirements of application fields.

2. The development of demand for high-performance organic pigments

With the advancement of science and technology, the demand for high-performance organic pigments and organic pigments with special functions will continue to increase; at the same time, the concept of environmental protection will be fully integrated into every link of organic pigment production, trade and consumption. The technological innovation of organic pigments should be market-oriented, accelerate the construction of a technological innovation system, attach great importance to original innovation, and rely on independent innovation to enhance the core competitiveness of the industry.

In the future, the scientific research and development of organic pigments should revolve around new products in the coatings, inks, plastics and other industries, improve the performance of old products, and develop new varieties of organic pigments that match them, so as to meet the constantly strict requirements of environmental protection regulations.

The requirements for the product can be summarized as: the high-grade product, that is, to meet the requirements of durability, weather fastness, heat resistance, solvent resistance and migration resistance of the metal surface coating; development of special products with high purity and specific crystal form Functional organic pigments, etc.; there are two intermediates of organic pigments that need attention, namely barbituric acid and phenyl cyanide and their para-derivatives. It is expected that in the next 5 to 10a, the former may replace 3,3'- Dichlorobenzidine, the latter is the main intermediate of diketopyrrolopyrrole (DPP) type organic pigments, these two intermediates are currently mainly used in the production of medicines.

As far as the coatings industry is concerned, with the technological progress in the fields of architectural coatings, automotive coatings, coil coatings and other coatings, the shortcomings of some organic pigments in coatings are constantly being exposed due to the demand for unique functions of coatings, which gives organic The development of pigments in the coatings industry has raised new issues. Organic pigment manufacturers have the responsibility to cooperate with the development of the coatings industry, develop and produce organic pigments that meet the needs of coatings, and create their own organic pigment brands.

As one of the most professional organic pigment manufacturers, we provide vivid blue pigment, indanthrone blue pigment, blue glow pigment, organic color pigments, etc. For more information, please feel free to contact us!

How to Choose Coating Pigments?(2023年)

shanhucolor — 2023-01-09T18:28:25+0900

https://www.shanhucolor.com/

Pigments are an important part of coatings. The most important role of coating pigments is to cover and impart color to the coating. In addition, it can protect and improve the application and mechanical properties of coatings. When choosing coating pigment, paint manufacturers should mainly focus on the following properties of pigments:

1. The particle size directly affects the hiding power and tinting power of the coating pigment. The smaller the particle, the greater the dispersion, the more the area of reflected light, and the greater the hiding power. For most coating pigments, the most effective particle size is one-half the wavelength of visible light. Tinting strength is the ability of a pigment to form a strong or weak color when mixed with another pigment. The smaller the particles, the greater the tinting power.

2. The shape of the coating pigment particles. The shape of the coating pigment particles mainly affects the fluidity, storage and durability of the paint.

3. Surface area of coating pigment particles. The specific surface area of a particle is defined as the surface area per unit mass of coating pigment. It is inversely proportional to the particle size. When the mass of the coating pigment particles remains constant, the particle size is reduced by half and the surface area is doubled.

4. Surface treatment of coating pigment raw material particles. With appropriate treatment, the surface of the coating pigment particles is either modified or completely replaced by a new surface.

5. Particle size distribution of coating pigment particles. Coating pigment is a solid particle, no matter what the manufacturing process is, it cannot be composed of a particle size, but has a certain distribution range.

In addition to providing color decoration for coatings, the role of pigments can also provide more improvements to the physical and chemical properties of coatings, such as hiding power, light resistance, weather resistance, temperature resistance, chemical resistance, gloss, mechanical strength, etc.

Ⅰ. What are coating pigments?
Coating pigment is a kind of fine powder colored substance, which is insoluble in water or oil medium, but can be uniformly dispersed in the medium, and is applied to the surface of the object to form a color layer to present a certain color. Pigment is an essential raw material in the coating process, it can make the coating have a certain covering ability, increase the color and protect the object. Colored pigments in the coating can also enhance the strength of the coating film, prevent the penetration of ultraviolet rays, and enhance the durability, weather resistance, and abrasion resistance of the coating film.

Pigments can be divided into two basic types, color pigments and system pigments (fillers). The most basic requirement for colored pigments is to impart color and opacity to the coating film, and can also have some other functions, such as anticorrosion, temperature indication, and luminescence. Colored pigments can be further classified into inorganic pigments and organic pigments. The properties of these two types of pigments are very different, and both inorganic and organic pigments are widely used in the coatings industry.

Pigment is also an essential component in the coating system, and the pigment is a secondary film-forming substance in the coating. The so-called pigment is a colored mineral or organic substance that is insoluble in binders (various film-forming substances).

Ⅱ. Classification of coating organic insoluble pigment
1. From the use of pigments, it is divided into three types: extender pigments, coloring pigments, and anti-rust pigments.
(1) Extender pigment: mainly used to increase the thickness of the coating, improve the wear resistance and mechanical strength.
(2) Coloring pigments: It has good covering properties and can improve the sun protection, durability and weather resistance of the coating. Some pigments can improve the abrasion resistance of the coating. And most importantly, color pigments can impart a variety of colors to the coating.
(3) Anti-rust pigment: This pigment can make the coating have good anti-rust ability and prolong life. It is the main raw material of anti-rust primer.

2. From the source of coating organic colour pigments, it can be divided into organic pigments and mineral pigments. Mineral pigments can be divided into natural pigments and artificial pigments.
(1) Mineral pigments: Mineral pigments are metal oxides or salts with complex structures. It is relatively stable to the effect of light and the atmosphere, and may form a film that protects the metal surface from corrosion. The most valuable mineral pigments are artificial pigments, which can be produced in a fixed color and shade on demand.
(2) Organic pigments: have rich colors and bright shades, but are inferior to mineral pigments in many properties. It still has value for use in less demanding finishing applications.

Generally most rubber coloring is black, gray or white, these are achromatic colors. In addition, there are many rubber products colored in colors, such as red, blue, yellow, green, brown, pink, etc. The coloring of rubber products can use organic pigments, inorganic pigments and dyes. Today we will mainly discuss organic pigments for rubber coloring. Organic pigments are used for coloring rubber because organic insoluble pigment can create bright and attractive color shades. By choosing the right pigment or mixing pigments, bright colors can be produced. Their advantage is that they produce a more beautiful appearance of the product.

2. The performance of rubber products
①It has good dispersibility in rubber medium, high tinting strength and covering power; excellent dispersibility makes the product have bright shade, high tinting strength, shortens rubber mixing time and reduces energy consumption.
② Excellent heat resistance stability, the colorant should keep the color unchanged during the heating molding process of the rubber product.
③Excellent vulcanization resistance and stability, the colorant does not react with the vulcanizing agent and accelerator. Some inorganic pigments chrome yellow lead or lead-containing pigments react with sulfur to form PBS and turn black, organic pigments should have vulcanization resistance.
④Excellent weather fastness, especially rubber products for building materials used outdoors.
⑤ Good chemical resistance, acid resistance, alkali resistance and water resistance.
⑥ Migration resistance, no color migration or color diffusion (B1eeding) or blooming due to the presence of softening (plasticizer) agents and lubricants during coloring.
⑦Do not affect the anti-aging performance of rubber products, some metal salts such as Cu, and Mn can accelerate the aging of rubber and reduce the mechanical strength.
⑧ Non-toxic, the coloring agent used for children's toys, food containers, medical appliances, and rubber products should not contain toxic substances. The unit cost of making natural paint pigments is much more expensive than inorganic pigments, but to make the color of the rubber color brighter and cleaner, organic pigments are necessary. Organic pigments are difficult to disperse in rubber compounds, and they are dustier in the application. In fact, they are usually used as rubber color master mixes. This pre-dispersed form solves dust problems, greatly improves color uniformity in the final product, and makes colorants easier to weigh and handle.

https://www.shanhucolor.com/products/pigment-red/

As an environmentally friendly ink, first of all, it meets the requirements of environmental protection, and the composition of the ink should be changed, that is, the new ink is formulated with environmentally friendly materials. At present, environmentally friendly inks mainly include water-based inks, UV inks, water-based UV inks and some alcohol-soluble inks.

1. Water-based ink
As a manufacturer of benzidine yellow and permanent orange pigments, you should understand the biggest difference between water-based inks and solvent-based inks, which is that the solvent used is water instead of organic solvents, which significantly reduces VOC emissions, prevents air pollution, and does not affect the human body. Healthy, non-flammable, stable ink, bright colors, non-corrosive plates, simple operation, low price, good post-press adhesion, strong water resistance, and rapid drying, so it is especially suitable for packaging and printed matters such as food, beverages, and medicines. The world-recognized environmentally friendly printing material is also the only ink approved by the US Food and Drug Association among all printing inks.

2. UV curable ink
Ultraviolet light-curing (UV) ink refers to the ink that uses ultraviolet light of different wavelengths and energies to make the ink film and dry under the irradiation of ultraviolet light. Using different ultraviolet spectra, different energy can be generated to polymerize monomers in different ink binders into polymers, so the color film of UV ink has good mechanical and chemical properties.

The main advantages of UV inks are:
(1) No solvent;
(2) Fast drying speed and low energy consumption;
(3) Good gloss and bright colors;
(4) Water resistance, solvent resistance and good wear resistance.

The photoinitiator in UV ink is a compound that is easily excited by light. After absorbing light, it is excited into free radicals, and the energy is transferred to photosensitive molecules or photocrosslinking agents, so that the UV ink undergoes a photocuring reaction. At present, UV ink has become a relatively mature ink technology, and its pollutant emission is almost zero. As a manufacturer of benzidine yellow and permanent orange pigments, you should know that in addition to being solvent-free, UV ink also has advantages such as not easy to paste, clear dots, bright and bright ink color, excellent chemical resistance, and low dosage.

3. Water-based UV ink
Water-based UV ink is a new direction of research in the field of UV ink. The viscosity of the prepolymer in ordinary UV ink is generally very large, and it needs to be diluted with a reactive diluent. The currently used diluent acrylate compounds have different degrees of skin irritation and toxicity. Therefore, while developing low-viscosity prepolymers and low-toxicity active diluents, another development direction is to study water-based UV inks, that is, water-based UV inks. and ethanol as diluents. At present, water-based UV ink has been successfully developed and applied in some printing.

In addition, alcohol-soluble ink, which mainly plays a role in flexo printing, is also a kind of ink with little pollution. It is mainly used in the packaging and printing of food, medicine, beverage, tobacco and alcohol, and daily necessities that come into contact with the human body.

Application of Organic Pigments in Coatings(2023年)

shanhucolor — 2023-01-09T18:24:15+0900

https://www.shanhucolor.com/products/pigment-violet/

1. The application of organic pigments
The applications of pigments mainly include coatings, inks, plastics, rubber, leather finishing, papermaking, ceramics, textiles, architecture, arts and crafts, medical care and cosmetics. Different application fields have different requirements for pigment performance, so pigments of different types and structures should be selected to meet the general needs of users.

2. The use of organic colour pigments in coatings
The current coatings often use phenolic resins, amino resins, alkyd resins, epoxy resins, nitrocellulose and natural resins as film-forming agents, and uniformly mix pigments into varnishes to make colored coatings. Generally, the requirements of coatings for pigments are high hiding power, light fastness and weather resistance, so inorganic pigments are used in many coatings. However, high-grade coatings that require high color brightness, such as automotive paints, also often use organic colour pigments, especially high-grade heterocyclic organic pigments, such as quinacridone, pyrrolopyrrole pigments, etc. Weather resistance and light fastness are ideal.

1. Organic Pigments
Pigments made from colored organic compounds are called organic pigments. Organic pigments refer to a class of pigments made from organic compounds that have color and a range of other pigment properties. Pigment properties include light fastness, water immersion resistance, acid resistance, alkali resistance, organic solvent resistance, heat resistance, crystal stability, dispersibility and hiding power.

2. Difference Between Organic And Inorganic Pigments
The difference between organic and inorganic pigments and dyes is that they have no affinity with the object to be colored, and only the organic colour pigments are attached to the surface of the object through adhesives or film-forming substances or mixed inside the object to color the object. The intermediates, production equipment and synthesis process required for its production are similar to the production of dyes, so organic pigments are often organized in the dye industry. Compared organic pigments vs inorganic pigments, organic pigments usually have higher tinting strength, the particles are easy to grind and disperse, not easy to precipitate, and the color is brighter, but the light fastness, heat resistance and weather resistance are poor. Organic pigments are widely used in the coloring of materials such as inks, coatings, rubber products, plastic products, stationery and building materials.

3. Overview
The organic color pigments are mainly azo pigments and phthalocyanine pigments, which account for more than 90% of the total organic pigments. The origin is mainly in Western Europe, the United States and Japan, and varieties such as aniline yellow G, toluidine red, lake red, and phthalocyanine are produced in China.

Pigments have a wide range of uses. Inorganic pigments are the main raw materials of coatings, such as architectural coatings, metal surface coatings and wood coatings are inseparable from titanium dioxide, chromium oxide, chrome yellow, etc. Titanium dioxide, chrome oxide yellow, ultramarine blue, and titanium yellow are used as colorants for plastics due to their heat resistance, light resistance, acid and alkali resistance, and migration resistance. Pigments are also used as organic pigment for printing ink because of their good flow and tinting strength. In addition, pigments are also used in rubber, paper, chemical fiber, painting, glass and other aspects.

4. Development Trend
①The development of pigments from general-purpose to special-purpose;
② Process improvements to improve quality and reduce costs have attracted more attention;
③ Strengthen the awareness of environmental protection and vigorously develop low-toxic pigments;
④ The production process is increasingly mechanized, automated and controlled by microcomputers.

Organic pigments are widely used and the demand is increasing day by day, so people are devoted to the development of natural organic pigments. In terms of its development trend, it has the following characteristics:
① While improving old strains, vigorously develop new strains;
②Adopt a new pigment ratio, improve the existing varieties, increase the value of use, and expand the scope of application;
③ Considering that the form of the pigment is easy to disperse the vehicle, and in order to prevent the dust from flying, the commercial dosage form produced is developed from powder to slurry.

What Are The Characteristics Of Organic Pigments, And What Are The Methods To Improve The Color Strength?(2023年)

shanhucolor — 2023-01-09T18:23:12+0900

https://www.shanhucolor.com/products/

1. The characteristics of natural organic pigments
Organic pigments are generally derived from plants and marine animals, such as indigo, garcinia, and ancient Roman purples extracted from shellfish. Organic pigments are bright in color and strong in tinting strength; low in density and non-toxic. Organic pigments look more frothy, while inorganic pigments are heavier. Organic pigments generally have higher brightness and higher tinting strength than inorganic pigments.

2. The tinting strength of organic pigments wiki
The tinting strength of organic pigments is mainly determined by their molecular chemical structure. Certain monoazo pigments, disazo pigments, phthalocyanine pigments, and heterocyclic pigments not only have bright colors but also give high tinting strength. For a specific chemical structure pigment, its particle size and distribution directly affect its tinting strength. The decrease in the average particle size of the pigment can lead to an increase in its tinting strength, that is, the tinting strength largely depends on the dispersion level of the pigment; coloring The intensity is not only dependent on the particle size, but also on the shape of the particles. Generally, flaky or slender particles can absorb light better and show a higher molar extinction coefficient. Aggregate particles, which are not conducive to the absorption of light.

3. Three primary colors of synthetic organic pigments
Organic pigments have bright colors and strong tinting strength; low density and non-toxicity, but some varieties are often inferior to inorganic pigments in light resistance, heat resistance, solvent resistance and migration resistance. The variety of colors is endless and colorful, but there is a certain internal relationship between various colors. Each color can be determined by 3 parameters, namely hue, lightness and saturation. Hue is a feature that distinguishes colors from each other. It is determined by the chromatographic composition of the light source and the perception of each wavelength emitted by the surface of the object to the human eye. It can distinguish red, yellow, green, blue, purple and other characteristics. Brightness, also known as brightness, is a characteristic value that represents the change in the degree of light and dark on the surface of an object; by comparing the lightness of various colors, the color can be divided into light and dark. Saturation, also known as chroma, is a characteristic value that represents the shade of color on the surface of an object, making the color different from bright and dark. Hue, lightness, and saturation form a solid and using these three to establish a scale, we can measure color numerically. The colors in nature are ever-changing, but the most basic ones are red, yellow, and blue, which are called primary colors.

4. Ways to Improve the Coloring Strength of Organic Pigments
Usually, on the basis of the molecular structure of the selected organic pigments, the organic tinting strength can be improved through the following main ways:

1. Strive to obtain products with fine particle sizes, such as adding a dispersant or a second diazo component and a second coupling component for mixing and coupling to prepare powder pigments with excellent dispersibility.

2. The pigment paste type is prepared by squeezing water and inverting the phase to prevent the particles from agglomerating during the drying process and improve the coloring strength of the product.

3. The water or organic solvent in the water-based or solvent-based pigment filter cake is removed by freeze-drying to obtain a powder with a loose texture and excellent dispersibility. Improve the tinting strength of the product.

4.At the same time, we should try to adopt high-efficiency dispersion equipment and effective modification treatment technology in the application process, such as bead mill, high-pressure homogenizer, critical liquid carbon dioxide treatment, latent pigment treatment, laser treatment and other technologies to make the pigment The particles are further refined to improve their coloring strength.

Pigment Application and Pigment Use

Print Ink
The print ink is mainly reflected by the color of the pigment.
The pigments used in industry must have high coloring power, chemical stability, and sun resistance. The organic pigment for printing ink in general ink binders are required to have good dispersion ability, and fine particles, and do not affect the fluidity of the ink after adding the ink.

Pigment Paste
The coloring of plastics is mainly inorganic and organic pigments for paints, which are required to have high coloring strength and brilliance.
The organic pigments uses are applied in different types of industries. The coloring power directly determines the amount of colorant. Generally speaking, the coloring power of organic pigments is much higher than that of inorganic pigments as the particle size of the colorant decreases. When color pigments are used together with white pigments, the coloring power can be significantly improved. Now with the technological growth of the organic pigment factory, organic pigments and ultra-fine particles of pigment paste manufacturers are widely used and developed.

Coatings
The pigment is the secondary film-forming material of the coating.
In addition to providing color decoration for the coating, the function of pigment can also provide more improvements in physical and chemical properties for the coating, such as covering, light resistance, weather resistance, temperature resistance, chemical resistance, gloss, and mechanical strength.
