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.
