Used as a photoinitiator in radical polymerization processes, particularly in UV-curable inks, coatings, and adhesives. It efficiently generates free radicals upon exposure to ultraviolet or visible light, enabling rapid curing under mild conditions. Its high thermal stability and solubility in organic matrices make it suitable for applications requiring long shelf life and consistent performance. Commonly employed in printing systems and electronic encapsulation where precise, fast curing is essential.
