2019-11-13 727

If there is a lack of gloss on the surface of a flat and smooth car paint surface, especially during the process of car paint care, it can be observed under a microscope that the surface is rough. What is the reason for this? Here is a brief analysis of automotive repair paint, as follows:

1、 Poor adhesion of the primer, or topcoat sprayed on it before the primer has fully cured.

2、 The quality of the materials used for ensuring the operation of the paint is too poor or the type is incorrect, or other incompatible additives are used.

3、 Due to the temperature being too high or too low, the drying speed of the coating is too slow.

6、 Solvent vapor or car exhaust has penetrated the surface of the paint film.

7、 The surface of the paint film is contaminated by wax, grease, oil, soapy water, or water.

8、 The use of overly aggressive detergents and cleaning agents in the newly sprayed paint film, as well as polishing too early after spraying the topcoat, or using too thick polishing paste.
