Used as a photoinitiator in UV-curable systems, this compound plays a key role in polymer chemistry, especially in inks, coatings, and adhesives that cure upon exposure to ultraviolet light. It enables rapid cross-linking of resins, offering efficient curing under low-energy UV sources. Its structure allows for good absorption in the UVA region and high reactivity, making it suitable for clear coatings and thin films where deep cure and low yellowing are important. Also found in some imaging systems and electronic encapsulation materials due to its stability and performance under controlled curing conditions.
