Used as a photoinitiator in UV-curable systems, enabling rapid polymerization of inks, coatings, and adhesives upon exposure to ultraviolet light. Its high efficiency and ability to generate free radicals make it suitable for clear and pigmented formulations, including printing inks, electronics encapsulation, and dental materials. Exhibits good thermal stability and compatibility with various monomers and oligomers, contributing to low migration and improved product durability. Also employed in specialty resins requiring high performance under demanding processing conditions.
