Highly efficient Type II photoinitiator with excellent reactivity under UV-A and visible light (365–405 nm).
Low yellowing tendency, delivering superior clarity and color stability in final cured films.
Excellent solubility in common acrylate monomers and oligomers, enabling homogeneous formulation blending.
Reduced migration potential due to high molecular weight and low volatility, supporting compliance with food-contact regulations.
Stable in storage at ambient temperature; compatible with standard industrial inkjet, coating, and adhesive formulations.
UV-curable inkjet inks for packaging and decorative printing.
Clear protective coatings for wood, plastic, and metal substrates.
Electronics encapsulants and conformal coatings requiring low outgassing.
Adhesives for optical bonding and display assembly.
3D printing resins demanding high resolution and minimal post-cure discoloration.
