Highly efficient Type I photoinitiator with excellent UV absorption at 265 nm and 320–370 nm.
Generates reactive benzoyl and methyl radicals rapidly upon UV exposure for fast polymerization onset.
Low yellowing tendency, supporting high-gloss and color-stable cured films in demanding applications.
Good solubility in common acrylate monomers and oligomers, including TMPTA, HDDA, and urethane acrylates.
Thermally stable up to 100 °C, enabling safe handling and storage under standard industrial conditions.
UV-curable printing inks for flexible packaging and label applications.
Coatings for wood, plastic, and metal substrates requiring high surface cure and hardness.
Electronic encapsulants and conformal coatings requiring low shrinkage and adhesion stability.
Dental composites and 3D printing resins (SLA/DLP) where rapid depth cure and biocompatibility are critical.
