Used as a photoinitiator in UV-curable systems, particularly in coatings, inks, and adhesives. It efficiently generates free radicals upon exposure to ultraviolet or visible light, enabling rapid polymerization of acrylate-based monomers and oligomers. Exhibits high thermal stability and low yellowing, making it suitable for clear and high-performance coatings. Also applied in advanced printing technologies and electronic encapsulation due to its excellent curing depth and reactivity under low-intensity light sources.
