Used as a photoinitiator in UV-curable systems such as inks, coatings, and adhesives. It efficiently generates free radicals upon exposure to ultraviolet light, enabling rapid polymerization of acrylate-based resins. Offers good solubility in polar monomers and exhibits low yellowing, making it suitable for clear and white formulations. Commonly employed in printing inks, electronic coatings, and dental materials where deep cure and stability are required.
