High reactivity under UV-A and visible light (365–405 nm) for rapid curing.
Low yellowing tendency, ensuring excellent clarity and color stability in final films.
Good solubility in common acrylate monomers and oligomers, enabling homogeneous formulation.
Reduced migration potential due to high molecular weight and low volatility.
Compatible with both free radical and hybrid (radical/cationic) photopolymerization systems.
UV-curable coatings for wood, plastic, and metal substrates.
Inkjet inks requiring low-odor, high-speed cure and excellent adhesion.
3D printing resins (SLA/DLP) demanding high resolution and low shrinkage.
Optical adhesives and protective films for displays and touch panels.
Decorative laminates and overprint varnishes for packaging and graphic arts.
