High reactivity under UV-A and visible light (365–405 nm), enabling efficient curing with LED sources.
Low migration and excellent extractables profile, supporting compliance with food-contact regulations (EU 10/2011, FDA 21 CFR).
Superior surface cure and through-cure balance in thick or pigmented formulations.
Good solubility in common acrylate monomers and oligomers, including HDDA, TPGDA, and urethane acrylates.
Thermally stable up to 120°C, minimizing premature decomposition during processing or storage.
UV-curable inks for flexible packaging and food-label printing.
Coatings for plastic substrates, including PET, PVC, and polycarbonate.
Adhesives for electronics assembly and medical device bonding.
3D printing resins requiring high-resolution detail and low shrinkage.
Overprint varnishes and functional topcoats in graphic arts applications.
