  • Applications

    Methyl perfluorobutyl ether (CAS 163702-07-6) is a specialty fluorinated ether solvent with high chemical stability and a suitable boiling range for industrial use. In practice, it is often used as a high-purity cleaning solvent for electronics and precision components; as a solvent or co-solvent/diluent for coatings, inks, and adhesives that require high performance; as a processing solvent or additive in the manufacture and testing of fluorinated polymers and fluoropolymers; as a component solvent in industrial formulations and QA workflows; and as a processing intermediate or formulation solvent in the synthesis of fluorinated compounds. Its use is subject to local regulations and formulation limits.
