Used as a photoinitiator in UV-curable systems, particularly in coatings, inks, and adhesives. It efficiently generates free radicals upon exposure to ultraviolet or visible light, enabling rapid polymerization of acrylate-based monomers and oligomers. Exhibits good thermal stability and solubility in polar organic solvents, making it suitable for clear coatings and thin films. Also applied in 3D printing resins where controlled, fast curing is required. Shows low yellowing after curing, which is beneficial in applications requiring optical clarity.
