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 cured films.
Good solubility in common acrylate monomers and oligomers, enabling homogeneous formulation blending.
Reduced migration potential due to high molecular weight and non-volatile nature.
Compatible with both free-radical and hybrid (radical/cationic) photopolymerization systems.
UV-curable coatings for wood and plastic substrates.
Inkjet inks requiring low-odor, high-speed curing on flexible packaging.
Optical adhesives and protective laminating films.
3D printing resins (SLA/DLP) demanding precise depth control and surface fidelity.
Electronics encapsulants and conformal coatings requiring thermal and chemical resistance.
