Title
(EN) CROSSLINKABLE FLUOROPOLYMER AND COATING FORMED THEREFROM
(FR) POLYMÈRE FLUORÉ RÉTICULABLE ET REVÊTEMENT FORMÉ À PARTIR DE CELUI-CI
Abstract
(EN) Provided is a high oil contact angle coating comprising fluoropolymer, compositions and processes for forming the coating, and articles comprising the coating. The fluoropolymer is a crosslinkable tetrapolymer fluoropolymer produced from the copolymerization of monomers tetrafluoroethylene, fluoro(alkyl vinyl ether) or fluoro(alkyl ethylene), alkyl vinyl ether and alkenyl silane. The fluoropolymer coating has high oil contact angle and utility as coating when the fluoropolymer is in the uncrosslinked or crosslinked state.
(FR) La présente invention concerne un revêtement à angle de contact élevé avec l’huile comprenant un polymère fluoré, des compositions et des procédés de formation du revêtement, et des articles comprenant le revêtement. Le polymère fluoré est un polymère fluoré de tétrapolymère réticulable produit à partir de la copolymérisation de monomères de tétrafluoroéthylène, de fluoro(éther d’alkyl vinyle) ou de fluoro(alkyl éthylène), d'éther d’alkyl vinyle et d'alcényle silane. Le revêtement de polymère fluoré présente un angle de contact élevé avec l’huile et une utilité en tant que revêtement lorsque le polymère fluoré se trouve à l’état non réticulé ou réticulé.
