Why is the adhesion of paint on plastic products poor?

Generally, there is no problem with the adhesion of ABS. If you want to improve the adhesion when paint peeling occurs, the effective solution is to use adhesion promoter to improve the adhesion between substrate and paint coating and solve the paint peeling problem. Electroplating is the most widely used process of ABS. If the release agent for injection molding sticks to the surface of ABS material, it will lead to oil spots, oil pits and oil spots on the surface during electroplating. Most industries use white electricity oil to soak and clean, and the output and effect are unstable. The effective solution is to fill electroplating oil stain treatment agent, cover oil stain, improve adhesion, and be halogen-free and heavy metal-free.
