Applications:

Uses

photoinitiator 819 can also be used for colored UV curing plastic coatings. UV coatings have been widely used on plastic shells of various electronic and home appliance products due to their excellent performance and efficient production. However, the UV coating film does not cure well after adding color, resulting in poor adhesion of the coating film, as well as the poor dispersion and arrangement of pigments by UV resin, it seriously affects the appearance of the coating film. Therefore, the traditional construction process is to first coat solvent-based colored primer for coloring, and then coat UV varnish after baking to improve the various physical properties of the paint film surface.

Uses

UV curable varnish and paint systems, such as wood, paper, metal, plastic, optical fiber and printing ink and prepreg systems
