Description

Bis(4-Dodecylphenyl)Iodonium Tetrakispentafluorophenylborate is a highly effective photoacid generator (PAG) and cationic polymerization initiator. This compound is valued for its excellent solubility in organic matrices and its ability to generate strong superacids upon UV irradiation or thermal activation. It is primarily needed by manufacturers in the electronics, advanced coatings, and specialty polymer industries for high-precision processes.

Application

• Photoacid Generator (PAG) for Advanced Photoresists: Critical component in chemically amplified resists (CARs) for semiconductor manufacturing and microelectronics lithography.
• Cationic UV-Curing Initiator: Used to initiate the rapid polymerization of epoxy and vinyl ether resins in coatings, inks, and adhesives cured by UV light.
• Thermal Latent Curing Agent: Employed in one-component epoxy systems and powder coatings where heat triggers the curing mechanism.
• Catalyst for Organic Synthesis: Acts as a strong Lewis acid catalyst in Friedel-Crafts alkylation and other acid-catalyzed organic reactions.
• Additive for Ionic Liquids & Electrolytes: Used in research and development of specialized ionic conductive materials.
