PL-BLK is a liquid photoinitiator compound developed specifically for black inks and coatings. It provides an optimum balance between surface cure and through cure to enable the best possible adhesion in these systems. Because of its optimum viscosity, it can be used in flexo, screen and paste inks without negatively effecting rheology. It is also well suited as a press side additive for the printer. PL-BLK is soluble in most monomers, oligomers and pre-polymers. It is insoluble in H2O.
