Bis(4-tert-butylphenyl)iodonium triflate (CAS 84563-54-2) is a highly efficient diaryliodonium salt widely used as a cationic photoinitiator and photoacid generator in UV-curable formulations. It is valued for its excellent photosensitivity, thermal stability, and ability to initiate rapid cationic polymerization, making it an essential component in advanced coating, adhesive, ink, and electronic material applications.
Upon UV exposure, this compound generates strong acids that efficiently initiate the polymerization of epoxy resins, vinyl ethers, oxetanes, and other cationically polymerizable monomers. Its high initiation efficiency and low yellowing characteristics make it suitable for high-performance UV-curing systems requiring excellent curing speed and long-term stability.
Bis(4-tert-butylphenyl)iodonium triflate is also used in photoresists, microelectronics, printed circuit boards, optical materials, and other precision manufacturing processes where reliable photoacid generation is critical.
