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.
