Typical solvents for the precursor fluorochemical amine are water miscible and include dimethyl formamide, dimethyl acetamide and N-methyl pyrrolidone, ketones such as acetone or methyl ethyl ketone, ethers such as tetrahydrofuran, and alkoxy ethanols, such as 2-ethoxy ethanol or 2-butoxy ethanol (e.g. Butyl Cellosolve).
