Used as a photoinitiator in UV-curable systems, particularly in inks, coatings, and adhesives. It generates free radicals upon exposure to ultraviolet or visible light, enabling rapid polymerization of acrylate-based resins. Offers good solubility in polar monomers and enhanced curing efficiency under low-intensity light sources. Also applied in 3D printing formulations where controlled, fast curing is required. Exhibits low yellowing, making it suitable for clear and color-sensitive applications.
