Used as a photoinitiator in polymer chemistry, particularly in UV-curable systems. It enables crosslinking of monomers and oligomers upon exposure to ultraviolet light, making it valuable in coatings, inks, and adhesives. Its boranuide structure enhances radical generation efficiency, allowing for rapid curing even under low-intensity UV light. Also employed in 3D printing resins where controlled, fast polymerization is required. Shows good solubility in polar organic solvents and compatibility with acrylate-based formulations.
