【Usage The photoinitiator 819 can also be used in colored UV-curable plastic coatings. UV coatings have been widely used in plastic shells of various electronic and household appliances products due to their excellent performance and efficient production. However, the deep curing of the UV coating film after coloring is not good, resulting in poor film adhesion, and the 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 paint the solvent-based colored primer first, After baking, UV varnish is applied to improve the physical properties of the film surface.
