Photoinitiator 819/Irgacure BAPO
Photoinitiator 819
Application: Photoinitiator 819 has been tested for printing inks and preimpregnation systems on wood, metal, plastic, paper and optical fiber surfaces.
In white paint, color paint and inks containing titanium white or other pigments with high hiding power, 819 adds a small amount to make the coating have excellent curing effect and UV yellowing resistance. Because of its excellent absorption properties, 819 can be used in thick film systems.
Photoinitiator 819 can be used in combination with other photoinitiators, such as photoinitiator 184 or photoinitiator 651. The combination of photoinitiator 819 and photoinitiator 651 is particularly suitable for curing polyester/styrene resin systems, such as glass fiber reinforced materials. Since it also absorbs in the long wave band, photoinitiator 819 can be used in combination with ultraviolet light absorbers, such as TINUVIN 400, so photoinitiator 819 can be applied to UV curable coatings that require weather resistance.
