High reactivity under LED UV-A (365–405 nm) and medium-pressure mercury lamp sources.
Low yellowing tendency, delivering excellent clarity and color stability in final cured films.
Excellent solubility in common acrylate monomers and oligomers, enabling homogeneous formulation blending.
Reduced odor and volatility compared to conventional TPO-type initiators, supporting safer handling and lower VOC emissions.
Good thermal stability up to 120 °C, minimizing premature decomposition during storage or processing.
UV-curable coatings for wood, plastic, and metal substrates.
3D printing resins (SLA and DLP) requiring high resolution and low shrinkage.
Electronic encapsulants and conformal coatings demanding optical transparency and adhesion.
Printing inks for packaging and decorative applications on flexible films and rigid boards.
Adhesives and laminating systems requiring rapid surface cure and deep-section polymerization.
