Used as a high-performance photoinitiator in advanced UV-curable resin systems, particularly in 3D printing and dental composites. Exhibits excellent thermal stability and deep curing capability due to efficient radical generation under long-wavelength UV light. Enables rapid polymerization with reduced oxygen inhibition, improving surface hardness and dimensional accuracy in printed or coated materials. Shows high compatibility with acrylate and methacrylate monomers, making it suitable for clear coatings, optical adhesives, and precision stereolithography applications.
