Highly efficient benzophenone-type photoinitiator with strong UV absorption at 320–365 nm.
Excellent compatibility with acrylate and epoxy-based UV-curable formulations.
Low volatility and superior thermal stability for extended shelf life and processing safety.
Minimal yellowing tendency, supporting high clarity and color fidelity in final cured films.
Acts synergistically with amine co-initiators to enhance surface cure and reduce oxygen inhibition.
UV-curable printing inks for flexible packaging and label applications.
Wood and plastic coatings requiring deep-section cure and scratch resistance.
Electronics encapsulants and conformal coatings demanding low migration and high reliability.
Optical adhesives and lens bonding systems where transparency and long-term stability are critical.
3D printing resins (SLA/DLP) requiring controlled reactivity and low odor profile.
