The field of plastic shell painting is very wide, involving all aspects of life, but in the actual plastic shell painting process, there is a phenomenon of paint spraying off the paint, such as non-polar material polypropylene PP material, low surface energy PA nylon material, PEI plastic steel, TR90 material, as well as the addition of fiberglass reinforced substrate, etc. Paint spraying process of the paint and the substrate adhesion is not enough to cause Poor adhesion of the paint film appeared paint firm enough to drop the paint problem. Then how to solve the problem of plastic shell spray paint off? First of all, the interlayer adhesion between the paint film and the substrate is an important factor in the coating firmly adhered to the surface of the material, so to enhance the adhesion between the paint and the surface of the plastic shell is the most important, but also an important way to solve the problem of paint. The primer-type adhesion treatment agent developed by Gui Sheng treatment agent is sprayed on the surface of the plastic shell to improve the polarity and wettability of the substrate, and by interacting with the paint film to form a chemical bond, the paint is firmly adhered to the substrate, thus solving the problem of paint dropout of the plastic shell and the adhesion reaches 5B in the 100-gauge adhesion test.
