PL-WHT is a liquid photoinitiator compound developed specifically for 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. Because it’s a liquid, it works well as a press side additive for the printer. PL-WHT is soluble in most monomers, oligomers and pre-polymers. It is insoluble in H₂O.
