Used as a photoinitiator in UV-curable systems, particularly in advanced coatings, inks, and adhesives. It efficiently generates free radicals upon exposure to ultraviolet light, enabling rapid polymerization of acrylate-based resins. Exhibits excellent thermal stability and low yellowing, making it suitable for high-performance clear coatings and sensitive printing applications. Also employed in some dental composite materials due to its deep curing capability and biocompatibility in formulated systems.
