Highly efficient cleavage-type photoinitiator with strong absorption in the UVA range (320–390 nm).
Enables rapid and deep cure in thick-section or pigmented UV formulations.
Low volatility and excellent thermal stability for extended shelf life and processing safety.
Compatible with acrylate-based monomers and oligomers, including multifunctional acrylates.
Minimal yellowing after curing, supporting high optical clarity in demanding applications.
UV-curable coatings for wood, plastic, and metal substrates.
Electronic encapsulants and conformal coatings requiring deep section cure.
3D printing resins (SLA/DLP) where fast reactivity and resolution are critical.
Pigmented inks for industrial inkjet and screen printing.
Adhesives for optical bonding and medical device assembly.
