Abstract: A method of making a fluoropolymer coating composition is described comprising blending a latex comprising crystalline submicron fluoropolymer particles with a latex comprising amorphous fluoropolymer particles. The method further comprises coagulating and drying the blended latexes and dissolving the dried blended latexes in a fluorinated solvent. Also described is a fluoropolymer (e.g. coating) composition comprising crystalline submicron fluoropolymer particles dispersed in a solution of fluorinated solvent and amorphous fluoropolymer; the fluoropolymer composition after removal of the solvent; and a substrate comprising a coated surface of the fluoropolymer composition. In each of these embodiments, he amorphous fluoropolymer comprises at least 90 wt-% of polymerized units derived from perfluorinated monomers selected from tetrafluoroethene (TFE) and one or more unsaturated perfluorinated alkyl ethers.

Abstract: A composition is described comprising at least one fluoropolymer. The fluoropolymer comprises at least 90% by weight based on the total weight of the fluoropolymer of polymerized units derived from perfluorinated monomers selected from tetrafluoroethene (TFE) and one or more unsaturated perfluorinated alkyl ethers and a fluorinated additive having a Mw of no greater than 50,000 g/mole comprising a partially fluorinated or perfluorinated alkyl or ether group. In some embodiments, the composition further comprises a fluorinated solvent. Also described are substrates comprising a coated surface of the fluoropolymer composition described herein.

Abstract: Described herein is coating composition comprising (a) a partially fluorinated polymer, wherein the fluorinated polymer comprises a C—F bond adjacent to a methylene (—CH2—) unit or a hydrohalogenated methylene (—CHX— where X is F, Cl, Br, or I) unit along the polymer backbone; (b) a protected amino silane; (c) an alkoxysilane; and (d) a non-fluorinated solvent. Also described herein are substrates coated with said coating composition and heated to bond the coating composition to the substrate.
