Full Description
Phenylglyoxylate-ester photoinitiators bridge the classic Type I and Type II classes and are prized for being liquid, low in odor and relatively low in migration and extractables. This blended/difunctional grade initiates free-radical polymerization of acrylate systems under UV and UV-LED sources and is widely used in clear coatings, overprint varnishes and inks where finished-article odor and extractable residue must be kept low. Because it is a liquid it is easy to dose and blend, and it is frequently combined with other photoinitiators to round out the cure response across the depth of the film. The material is classified as a skin sensitizer; handle per its safety data sheet
