  • Applications

    Ethyl perfluoroisobutyl ether (CAS 163702-06-5) is a specialty fluorinated ether used as a solvent and processing aid in niche industrial applications. Typical use areas include electronics manufacturing (precision cleaning of metal components and photoresist processing), coatings and fluorinated ink formulations (solvent/carrier for fluorinated resins), processing and formulation of polymers and composite materials (solvent or processing aid for fluorinated polymers and coatings), acting as an intermediate in the synthesis of specialty fluorinated chemicals, and precision cleaning of aerospace/automotive components. Its use is subject to local regulations and formulation limits.
