The adhesion of the sealing tape refers to the force between the tape and the stuck object. The adhesion of adhesive tape not only depends on the surface structure and state of adhesive and adherend, but also is closely related to the technological conditions of the bonding process. Next, the factors that affect the adhesion of the sealing tape will be introduced.

Factors in the production process: the polarity of the adhesive is too high, which sometimes seriously hinders the wetting process so that the adhesion will be reduced. The intermolecular force is the force of attraction between the adhesive and the adhered, including van der Waals force and hydrogen bond, with the action distance of 0.3 ~ 0.5nm. The mechanical adhesion is the adhesion force produced by the adhesive molecules after penetrating into the pores of the surface of the adhered and curing. Although the mechanical insertion force is very small, it can not be ignored. Chemical bond force is the chemical bond that can be formed between the adhesive and the surface of the adhered, including covalent bond, valence bond, ion bond, metal bond, etc. The bond energy is much higher than the intermolecular force, and the chemical bond is very strong, which has a great influence on the bond strength.

Influence of environment on adhesive tape: sometimes we will find that adhesive tape is reduced. What is the reason? When the tape is used for a long time and is affected by moisture, its viscosity will be greatly reduced. At the same time, its viscosity is also affected by the temperature. When the low temperature reaches a certain degree, its viscosity is not as strong as the original. If we work in a low ambient temperature, we can heat the tape in a suitable "oven" to improve its adhesion.

Dongguan Hyseal Co., Ltd was founded in 2009. It is located in the north area of Dongguan city, just 40kms to Guangzhou and 80kms to Shenzhen.
