On the PP plastic surface spray paint always fall off the problem

PP plastic spray paint coating easy to fall off the main reason is because PP plastic belongs to the non-polar substrate, it is difficult to oil, generally need to be pre-treatment process to improve the adhesion of the substrate surface, to enhance the combination with the paint, the formation of a solid paint coating.

Common PP plastic surface treatment methods are flame treatment, corona treatment and Shizukawa PP treatment agent, flame treatment and corona treatment of the adhesion effect is difficult to control, equipment and operation of the process is cumbersome, PP treatment agent is relatively easy to operate, enhance the adhesion effect is obvious.

The use of PP treatment agent is through the primer construction method, the PP plastic surface cleaning and cleaning, spraying treatment agent, and then spray paint, and sprayed with a high degree of integration of the line body, but also applies to the PP modified material spray paint process.
