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 sources.
Excellent thermal stability up to 120 °C, supporting high-speed coating and printing processes.
Low migration profile, suitable for applications requiring regulatory compliance (e.g., ISO 10993, FDA indirect food contact).
Non-yellowing performance in clear and pigmented formulations, preserving optical clarity and color fidelity.
UV-curable industrial coatings for metal, plastic, and wood substrates.
Electronics encapsulants and conformal coatings requiring low shrinkage and high adhesion.
3D printing resins for stereolithography (SLA) and digital light processing (DLP) technologies.
Optical adhesives and lens bonding formulations demanding high transparency and refractive index stability.
Overprint varnishes and decorative laminates in packaging and graphic arts.
