Purpose of pretreatment in the processing of PVC wood grain steel plate: Before spraying PVC wood grain steel plate and plate, the surface of the workpiece should be decontaminated and chemically treated to form a chromed film, and to increase the adhesion and resistance of the coating to the metal surface. The oxidation ability is beneficial to prolong the service life of the paint film.
Finishing paint coating in the processing of PVC wood grain steel plate: the finishing paint coating is also called varnish coating. The color is more obvious and the light is dazzling, and the coating thickness is generally 5-10 microns. The total thickness of the three-spray coating is generally 40-60 microns, and it can be thickened for special needs.
