Application
Photoinitiator 819 is a high effective UV photoinitiator, which is used to
initiate the UV polymerization of unsaturated prepolymer system. It has been
widely used in coatings, inks, adhesives and other industries for their excellent
properties. It has great absorption in the ultraviolet and visible regions, and
can initiate curing more effectively than other photoinitiators for coatings
containing pigments. It hardly yellows after curing and long-term light radiation,
so it can be used in occasions where yellowing requirements are stricter, such as
white, light ink and paint. In addition, it has bleaching effect on light, which
can penetrate the coating and help the thick film to be cured thoroughly.
