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.
