Influencing factors of adhesion of plastic spraying UV paint for vacuum electroplating electric heating pipe

In the coating process, the more commonly used paints are ordinary paint (generally based on color paint), rubber paint, PU paint, UV paint, etc., each with its own advantages and disadvantages, depending on the needs of the coating. Here we mainly take a look at the process of spraying UV paint on the surface of plastic materials and how to solve the problem of coating adhesion?

Adhesion is the basic and important requirement of the coating for the surface treatment work of plastic sprayed UV paint. However, due to the difference of the material to be coated, it can have a direct impact on the adhesion of UV paint. Therefore, the material has differences in polarity, crystallinity, and surface energy, surface tension and other properties. These factors are all factors that cause the adhesion of plastic spray UV paint.

Vacuum electroplating electric heating tube material painting process

TR90 treatment agent is suitable for TR90 material painting process. It has wide versatility. It has good adhesion and excellent flexibility to pure TR90 materials or TR90 miscellaneous materials. In addition to basic adhesion tests such as 100 grids, it can withstand freezing. The test bending does not show the phenomenon of paint explosion. The construction process is simple, and after cleaning the surface of the material, spray TR90 treatment agent, and the oiling performance is good.

Falling paint not only affects the surface painting effect of the spectacle frame, but also is an important guarantee for the protective performance and decorative performance of the coating. So how to solve the problem of paint falling off of the TR90 spectacle frame, the adhesion becomes the key point.

Vacuum electroplating electric heating tube paint film coating

Spray paint belongs to oil spray processing, which is affected by many process and material factors. It is necessary to make the surface of the spectacle frame spray paint with a good paint film coating and pass a number of adhesion performance tests| (such as 100 grid, freezing, knife cutting, Bending, etc.), in addition to strict process conditions, it is important to improve the interlayer adhesion between the TR90 substrate and the paint coating.
