PL-CLR is a liquid photoinitiator compound developed specifically for thicker clear films where low yellowing is necessary. It provides a perfect balance between surface cure and through cure to enable the best possible adhesion in these systems. Because it’s a liquid, it works well as a press side additive for the printer.

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