Used as a photoinitiator in UV-curable systems, particularly in inks, coatings, and adhesives. It enables rapid polymerization upon exposure to ultraviolet light, offering efficient curing even under low-intensity UV sources. Its high reactivity and low yellowing make it suitable for clear coatings and sensitive applications. Also employed in 3D printing resins where precise curing and stability are required. Shows good performance in combination with other photoinitiators to broaden the absorption range and improve cure depth.
