Technical application of PP treatment agent in spray paint of polypropylene PP plastic

When PP plastic is sprayed or glued, usually a layer of PP treatment agent /PP water is applied to the bottom of the PP plastic surface to pre-treat the substrate, and then spray paint or glue. Why should I enter the primer? In fact, the spray paint industry has a lot of knowledge about primer adhesion enhancement. As for the effect and principle of PP treatment agent/PP water, how much do you know? Let's take a look at this now.

Analyzing the undesirable phenomena of PP plastic spray paint , it is believed that PP treatment agent can solve the problems of ordinary color paint, rubber paint, UV paint and PU paint of PP plastic spray paint, and there are problems such as failure to meet the test standards and paint film peeling. In the field of viscose, it is used to solve the degumming phenomenon caused by insufficient bonding between PP plastic and glue, such as the bonding of PP plastic and water-based polyurethane glue, not being tightly bonded to the substrate, pulling and other testing degumming.

The application of PPPP water/PP treatment agent in the spray paint of polypropylene PP plastics.

From the perspective of the phenomenon, the essence is related to the principle of the PP treatment agent. In a simple summary, it is to strengthen the bonding of the substrate and the coating or glue. According to the theory of bonding strength, the PP treatment agent can wet the surface of the substrate well, and the thickness of the formed film can improve the adhesion of the coating to the film. Chlorinated polypropylene diffuses into the substrate, fully wets the surface of the substrate to enhance the intermolecular force, and improves the adhesion of the material surface through chemical bonds and surface chemical bonds.

PP plastic coating is of great significance for extending the life cycle of plastic products and meeting the weather resistance and decoration of the environment in which it is used. Adhesion is the basis of coating, and only PP plastic coating can meet the above requirements. When PP spray paint or adhesive encounters a bad problem, there are multiple solutions to choose from. It is necessary to choose a suitable, simple and stable method. In summary, the PP treatment agent/PP water can solve the problem of PP spray paint and glue sticking. An excellent solution to problems such as paint and degumming.
