Plastic PVD vacuum coating process-primer painting
Vacuum coating process requires good cooperation between the surface of plastic products and primer, primer thickness is usually 15 -- 25 m, the main role is to prevent the plastic water, organic solvent, plasticizer and other discharge affect the metal adhesion. High hardness of coating, primer can modify plastic defects, can provide a smooth, flat surface to facilitate the performance of vacuum coating, such as fullness, glossiness and adhesion, and to ensure that the plastic substrate and the gold plate adhered firmly. Two-component urethane and epoxy coatings, amino coatings for low-temperature baking, and thermoplastic acrylates are commonly used.
