High reactivity under UV-A and visible light (365–405 nm), enabling efficient curing with LED sources.
Low yellowing tendency, delivering excellent color stability in clear and white coatings.
Good solubility in common acrylate monomers and oligomers, ensuring homogeneous formulation blending.
Reduced migration potential due to its high molecular weight and non-volatile nature.
Compatible with both free-radical and cationic hybrid systems for enhanced formulation flexibility.
UV-curable industrial wood coatings requiring low odor and high surface cure.
LED-curable printing inks for flexible packaging and label applications.
Optical adhesives and protective coatings for electronics and displays.
3D printing resins demanding precise depth control and minimal post-cure shrinkage.
Overprint varnishes and functional coatings on plastic and metal substrates.
