Photoinitiator 819 can also be used for colored UV-curable plastic coatings. UV coatings have been widely used on the plastic shells of various electronic and household appliances due to their excellent performance and efficient production. Poor curing results in poor adhesion of the chemicalbook film, and poor dispersion and arrangement of the UV resin on the pigment, which seriously affects the appearance of the coating film. Therefore, the traditional construction process is to first coat a solvent-based colored primer for coloring, and then bake it. Then apply UV varnish to improve the various physical properties of the paint film surface.
