PL-4265 is a 50:50 liquid blend of 2-hydroxy-2-methyl-1-phenyl-1-propanone and diphenyl (2,4,6-trimethylbenzoyl) phosphine oxide. It provides exceptional cure response in white and pastel pigmented systems as well as thicker clear films. It provides a perfect balance between surface cure and through cure to enable the best possible adhesion in these systems.

PL-4265 soluble in most monomers, oligomers and pre-polymers. It is insoluble in H2O.
