Highly efficient cationic photoinitiator for UV-curable epoxy and vinyl ether systems.
Enables rapid polymerization under low-intensity UV or LED light sources (365–405 nm).
Excellent thermal stability up to 120 °C, supporting high-temperature processing and storage.
Low volatility and minimal odor—ideal for indoor and enclosed-cure applications.
Compatible with common reactive diluents and oligomers in industrial coatings and inks.
UV-curable protective coatings for electronics and optical components.
High-gloss decorative coatings on wood, metal, and plastic substrates.
Industrial adhesives requiring deep-section cure and low shrinkage.
3D printing resins for stereolithography (SLA) and digital light processing (DLP).
Overprint varnishes and functional barrier coatings in packaging.
