This invention teaches novel fluoropolymer nanoemulsion products and process. The fluoropolymer nanoemulsions comprise at least 20% by weight of colloidal fluoropolymer nano-particles with average diameter in the range of 1 to 150 nanometer, 0.1% to 3.0% by weight of halogenated dispersing agents selected from fluoro surfactants, chlorofluoro surfactants, hydrofluoro surfactants, or hydrochlorofluoro surfactants, and any CFC (chlorofluorocarbon) or HFC (hydrofluorocarbon) or any HCFC (hydrochlorofluorocarbon) or any CC (chlorocarbon) was mostly removed from the nanoemulsion to be less than 0.5% by weight of the nanoemulsion. |
