15 Claims

1. A composition comprising

at least one fluoropolymer, wherein the at least one fluoropolymer comprises at least 90% by weight based on the total weight of the at least one fluoropolymer of polymerized units derived from perfluorinated monomers selected from tetrafluoroethene (TFE) and one or more unsaturated perfluorinated alkyl ethers;

a fluorinated solvent; and

a fluorinated additive having a Mw of no greater than 50,000 g/mole comprising a partially fluorinated or perfluorinated alkyl or (poly)ether group and a silane group; wherein the fluorinated additive has a concentration in the range of 10 to 50 wt. % solids.
