Plastic paint is actually a paint. It is very common in metal or plastic surface treatment process. It is a one-component paint that does not need to add curing agent. It has high hardness, high gloss, high fullness, and interlayer adhesion. With good performance and easy construction, it is widely used in the coating of plastic substrates. Such as plastic toys, plastic daily necessities, electrical products, plastic handicrafts and other surface coating processes.
In the process of spraying plastic on the surface of plastic material, the basic requirement for a good coating effect is that the adhesion is strong enough to ensure adequate adhesion of the paint on the surface of the substrate and no problem of paint removal occurs. However, plastic materials such as nylon and PP are used. Due to the polarity or the surface energy and the composition of the material, the poor adhesion of paint will occur after spraying the plastic paint. This will affect the progress and quality of the paint. The metal surface sprayed plastic paint also encountered similar problems, but the metal Spray paint is generally less.
So how does plastic and metal surface spray plastic paint improve adhesion? There are many methods in the industry, but there are many deficiencies and deficiencies. The effective solution is to apply an adhesion treatment agent on the surface of plastic and metal materials. To improve the adhesion between the material and plastic paint, through the polar functional group or molecular diffusion, mechanical bite, etc., to improve the adhesion of the paint film, through the adhesion test.
In order to solve the problem of adhesion of plastic or metal spray plastic paints, Adhesive Adhesion Treatment Agent must have a certain process flow in the coating process. Cleaning and degreasing are important pre-treatment processes. Hand spray or automatic line In the spraying process, the effect of the adhesion treatment agent can maintain a good applicability of the coating environment.
