Used as a high-performance photoinitiator in UV-curable systems, particularly in advanced coatings, inks, and adhesives. It exhibits strong absorption in the long-wavelength UV to near-visual light range, enabling efficient curing under low-intensity light sources and improved performance in thick or pigmented formulations. Its high molar extinction coefficient and excellent radical generation efficiency make it ideal for applications requiring deep curing and rapid polymerization. Commonly employed in industrial printing, electronics encapsulation, and 3D printing resins where precise and complete curing is critical. Shows good thermal stability and compatibility with various monomer and oligomer systems, enhancing formulation flexibility.
