The present disclosure relates to a method of treating a substrate comprising an elastomeric material, wherein the method comprises the steps of: a) providing a composition comprising: i. at least one fluoropolymer which is a copolymer comprising at least 90% by weight, based on the total weight of the copolymer, of units derived from tetrafluoroethene (TFE) and from one or more perfluorinated alkyl ethers corresponding to the general formula (I): R&#x2014;O&#x2014;(CF)&#x2014;CF&#x2550;CF(I) wherein n is 1 or 0 and Rrepresents a perfluoroalkyl residue which is optionally interrupted once or more than once by an oxygen atom; and ii. at least one solvent comprising a linear, cyclic or branched, partially fluorinated (poly)ether; b) contacting at least part of the substrate with the composition of step a); c) at least partially removing the at least one solvent; and d) optionally, when the fluoropolymer is curable, subjecting the fluoropolymer to curing, wherein the curing step may be carried out simultaneously with or after step c).

Fluoropolymer coatings for substrates comprising an elastomeric material

A composition comprising at least one fluoropolymer and at least one solvent, wherein the solvent comprises a branched, partially fluorinated ether and wherein the partially fluorinated ether corresponds to the formula:CF&#x2014;O&#x2014;CHwherein q is an integer from 1 to and 5 and p is an integer from 5 to 11; and wherein the fluoropolymer is a copolymer comprising at least 90% by weight (based on the total weight of the polymer, which is 100% by weight) of units derived from tetrafluoroethene (TFE) and one or more perfluorinated alkyl ethers selected from ethers corresponding to the general formulaR&#x2014;O&#x2014;(CF)&#x2014;CF&#x2550;CFwherein n is 1 in which case the ether is an allyl ether, or 0 in which case the ether is a vinyl ether and Rrepresents a perfluoroalkyl residue which may be interrupted once or more than once by an oxygen atom. Also provided are methods of preparing the compositions and methods for coating substrate with the compositions.
