Used as a photoinitiator in UV-curable systems, particularly in inks, coatings, and adhesives. It efficiently generates free radicals upon exposure to UV or visible light, enabling rapid polymerization of acrylate-based resins. Offers good solubility in polar monomers and enhanced performance in low-odor formulations. Commonly selected for applications requiring deep cure and minimal yellowing, such as in dental materials and clear protective coatings.
