Widely used as a photoinitiator in UV-curable systems, this compound plays a key role in inks, coatings, and adhesives that require rapid curing under ultraviolet light. It efficiently generates free radicals upon UV exposure, initiating polymerization of monomers and oligomers. Its high thermal stability and compatibility with various resin systems make it suitable for clear coatings and printing inks where yellowing must be minimized. Additionally, it is employed in specialty applications such as lithography and electronic encapsulation due to its reliable performance under controlled UV exposure.
