Highly efficient cationic photoinitiator for UV-curable epoxy and vinyl ether systems.
Enables rapid polymerization under low-intensity UVA (320–395 nm) and visible light exposure.
Excellent thermal stability up to 180 °C, supporting high-temperature processing and storage.
Low volatility and non-migrating character, ensuring consistent film integrity and regulatory compliance.
Compatible with common reactive diluents and resins without significant inhibition or yellowing.
UV-curable industrial coatings for metal and plastic substrates.
Electronics encapsulants and conformal coatings requiring low shrinkage and high adhesion.
3D printing resins for stereolithography (SLA) and digital light processing (DLP) platforms.
Optical adhesives and lens bonding formulations demanding optical clarity and long-term stability.
Photopolymerizable inks for packaging and decorative printing on rigid substrates.
