Highly efficient cationic initiator for epoxy and vinyl ether resins under ambient or mild thermal conditions.
Excellent thermal stability with onset decomposition temperature above 200 °C.
Low volatility and negligible vapor pressure, enhancing workplace safety and formulation handling.
Superior compatibility with a broad range of epoxy monomers and oligomers, including bisphenol-A and novolac epoxies.
Non-hygroscopic solid form ensuring long-term storage stability without refrigeration.
UV-curable and dual-cure (UV/thermal) coatings for industrial metal and plastic substrates.
High-performance encapsulants and potting compounds in electronics and power module manufacturing.
Adhesives for aerospace composites requiring low outgassing and high glass transition temperature (Tg).
Electrical insulation varnishes and impregnating resins for motors, transformers, and generators.
