819 is a highly efficient, general-purpose UV photoinitiator used to initiate UV polymerization of unsaturated prepolymerization systems.
819 also absorbs visible light in the long-wavelength band above 400nm, especially suitable for deep curing and thick film systems. 
It can also be used with UV absorbers for UV-curable coatings that require weather resistance.
819 can be used in printing inks and prepreg systems for wood, metal, plastic, paper and fiber surfaces, as well as white lacquers with high opacity, paints and inks containing titanium white or other pigments.
Package: 25kg/drum, can also be designed according to customer requirements.
Storage: Store in cool place. Keep container tightly closed in a dry and well-ventilated place.
