Used as a highly effective photoinitiator in UV-curable systems, particularly in advanced printing inks, coatings, and adhesives. Exhibits excellent performance in free radical polymerization under low-intensity UV light, enabling rapid curing even in shadowed or thick sections. Shows good solubility in polar monomers and resins, making it suitable for formulations requiring high clarity and low yellowing. Also employed in 3D printing resins where efficient initiation and depth of cure are critical. Its unique molecular structure provides enhanced thermal stability and reduced migration, beneficial for food packaging and medical applications.
