Used as a photoinitiator in UV-curable systems such as coatings, inks, and adhesives. It efficiently generates free radicals upon exposure to ultraviolet light, enabling rapid polymerization of acrylate-based resins. Offers good thermal stability and low yellowing in clear coatings, making it suitable for high-performance and aesthetic-sensitive applications. Also employed in 3D printing resins where precise curing and minimal odor are desired.
