Used as a photoinitiator in UV-curable systems, enabling rapid polymerization of inks, coatings, and adhesives upon exposure to ultraviolet light. Its ability to generate free radicals under UV irradiation makes it effective in clear and pigmented formulations, including printing inks and electronic materials. Exhibits good solubility in monomers and oligomers, supporting stable performance in various resin systems. Suitable for applications requiring low yellowing and high reactivity, especially in thin-film curing processes.
