Used as a photoinitiator in UV-curable formulations, enabling rapid polymerization of inks, coatings, and adhesives upon exposure to ultraviolet light. It is particularly effective in clear coatings and pigmented systems due to its ability to generate free radicals efficiently under UV-A and visible light. Offers good yellowing resistance and storage stability, making it suitable for high-performance industrial and graphic arts applications. Also employed in 3D printing resins where controlled curing and depth of cure are critical.
