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 pigmented coatings.
Good solubility in common acrylate monomers and oligomers, enabling homogeneous formulation without crystallization.
Reduced migration potential due to higher molecular weight and low volatility.
Compatible with both free-radical and hybrid (radical/cationic) photopolymerization systems.
UV-curable wood coatings for furniture and flooring.
Overprint varnishes and decorative inks for flexible packaging and labels.
3D printing resins requiring low shrinkage and high surface cure.
Industrial UV-curable adhesives and laminating varnishes.
Clear protective topcoats for automotive trim and electronics enclosures.
