Photoinitiator 819 function:

Photoinitiator 819 can also be used in colored UV-curable plastic coatings. UV coatings have been widely used in plastic housings of various electronic and home appliance products due to their excellent performance and efficient production, but UV coatings are added after coloring. Poor curing, resulting in poor adhesion of the coating film, and poor dispersion of the pigment by the UV resin, seriously affecting the appearance of the coating film, so the traditional construction process is first painted with a solvent-based colored primer for coloring, after baking Apply UV varnish to improve the physical properties of the paint film surface.

UV-curable varnishes and paint systems, such as wood, paper, metal, plastic, fiber optics, and printing inks and prepreg systems.
