Highly efficient Type II photoinitiator with excellent reactivity under UV-A and visible light (365–405 nm).
Low yellowing tendency, delivering superior color stability in clear and white coatings.
Good solubility in common acrylate monomers and oligomers, enabling easy formulation integration.
Reduced migration potential due to higher molecular weight and limited volatility.
Compatible with both free-radical and hybrid (radical/cationic) UV-curing systems.
UV-curable wood coatings for furniture and flooring.
Decorative and functional inks for digital inkjet printing (e.g., on rigid plastics and glass).
Optical adhesives and protective overprint varnishes requiring low odor and high clarity.
3D printing resins (SLA/DLP) where low shrinkage and high surface cure are critical.
Electronics encapsulation and conformal coatings demanding thermal stability and low ionic impurities.
