PL-229W is a liquid photointitiator 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.
