Photoinitiator 819 can also be used for colored UV cured plastic coatings,
UV coatings have been widely used on plastic shells of various electronic and household appliances due to their excellent performance and efficient production. However, the deep curing of UV coatings after coloring is not good, resulting in poor adhesion of the coatings and poor dispersion and arrangement of pigments by UV resin, which seriously affects the appearance of the coatings. Therefore, the traditional construction process is to first apply solvent based colored primer for coloring, then apply UV varnish after baking to improve the various physical properties of the coating surface.
