PL-IND is a liquid photoinitiator compound developed specifically for dark and black inks and coatings where acid adhesion promoters are present.. It provides an optimum balance between surface cure and through cure to enable the best possible adhesion in these systems. Because of it’s optimum viscosity, it can be used in most coating and ink systems without negatively effecting rheology. It is also well suited as a press side additive for the printer

PL-IND is soluble in most monomers, oligomers and pre-polymers. It is insoluble in H2O.
