Title (EN) FLUOROPOLYMER COMPOSITIONS AND COATINGS
(FR) COMPOSITIONS ET REVÊTEMENTS DE FLUOROPOLYMÈRE
Abstract:
(EN) 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: Rf-O-R wherein Rf is a perfluorinated or partially fluorinated alkyl group that may be interrupted once or more than once by an ether oxygen and R is a partially fluorinated or a non-fluorinated alkyl group; 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 formula Rf-O-(CF2)n-CF=CF2 wherein n is 1 in which case the ether is an allyl ether, or 0 in which case the ether is a vinyl ether and Rf represents 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.
(FR) La présente invention concerne une composition comprenant au moins un polymère fluoré et au moins un solvant, le solvant comprenant un éther ramifié, partiellement fluoré et l'éther partiellement fluoré correspondant à la formule : Rf-O-R dans laquelle Rf est un groupe alkyle perfluoré ou partiellement fluoré qui peut être interrompu une ou plusieurs fois par un oxygène d'éther et R est un groupe alkyle partiellement fluoré ou non fluoré ; et le polymère fluoré étant un copolymère comprenant au moins 90 % en poids (par rapport au poids total du polymère, qui est de 100 % en poids) de motifs dérivés du tétrafluoroéthène (TFE) et d'un ou de plusieurs éthers d'alkyle perfluorés choisis parmi les éthers correspondant à la formule générale Rf-O-(CF2)n-CF=CF2 dans laquelle n est 1 auquel cas l'éther est un éther d'allyle, ou 0 dans lequel cas l'éther est un éther de vinyle et Rf représente un résidu perfluoroalkyle qui peut être interrompu une ou plusieurs fois par un atome d'oxygène. L'invention concerne également des procédés de préparation des compositions ainsi que des procédés de revêtement de substrat avec les compositions.
