Highly efficient Type II photoinitiator with excellent reactivity under UVA and visible LED light sources (365–405 nm).
Low yellowing and superior photostability, ensuring long-term clarity in demanding optical and decorative coatings.
Excellent solubility in common acrylate monomers and oligomers, enabling homogeneous formulation without crystallization issues.
Reduced odor and low volatility compared to traditional benzophenone derivatives, supporting safer industrial handling.
Good surface cure performance even under inert (nitrogen) atmospheres, enhancing versatility in high-speed coating lines.
UV-curable clearcoats for automotive and plastic trim finishing.
LED-curable inks for digital inkjet printing on rigid substrates.
Optical adhesives and laminating resins requiring high transparency and low extractables.
3D printing resins (SLA/DLP) where low shrinkage and high resolution are critical.
Wood and paper coatings demanding fast through-cure and minimal migration.
