High reactivity under UV-A and visible light (365–405 nm) for rapid cure kinetics.
Excellent surface cure and low oxygen inhibition, enabling efficient free-radical polymerization.
Good solubility in common acrylate monomers and oligomers, ensuring homogeneous formulation stability.
Low volatility and negligible migration, supporting compliance with food-contact and medical device regulations.
Thermally stable up to 180 °C, allowing compatibility with high-temperature processing steps.
UV-curable coatings for wood, plastic, and metal substrates.
Inkjet inks for industrial and decorative printing applications.
3D printing resins (SLA/DLP) requiring high resolution and mechanical robustness.
Optical adhesives and encapsulants for electronics and LED assembly.
Dental composites and restorative materials demanding biocompatibility and fast intraoral curing.
