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