Used as a photoinitiator in UV-curable formulations, enabling rapid polymerization of inks, coatings, and adhesives upon exposure to ultraviolet light. It is particularly effective in free radical polymerization processes, offering good reactivity and low yellowing in clear coatings. Commonly found in printing inks, electronic encapsulants, and industrial coatings where efficient curing under UV light is required. Its molecular structure supports cleavage under UV radiation to generate initiating radicals, making it suitable for applications demanding fast curing and high performance.
