Title
(EN) POWDER COATING COMPOSITIONS COMPRISING A POLYESTER AND A FLUOROPOLYMER AND COATINGS FORMED THEREFROM
(FR) COMPOSITIONS DE REVÊTEMENT EN POUDRE COMPRENANT UN POLYESTER ET UN FLUOROPOLYMÈRE ET REVÊTEMENTS FORMÉS À PARTIR DE CELLES-CI
Abstract
(EN)
A powder coating composition can include: a polyester polymer having carboxylic acid functional groups; a first crosslinker reactive with the carboxylic acid functional groups of the polyester polymer; and a fluoropolymer unreactive with the polyester polymer and first crosslinker. A weight ratio of the polyester polymer to the fluoropolymer is from 80:20 to 60:40. When cured, the powder coating composition forms a single coating layer including the polyester polymer and the fluoropolymer.
(FR)
Une composition de revêtement en poudre peut comprendre : un polymère de polyester ayant des groupes fonctionnels d'acide carboxylique ; un premier agent de réticulation réagissant avec les groupes fonctionnels d'acide carboxylique du polymère de polyester ; et un polymère fluoré non réactif avec le polymère de polyester et le premier agent de réticulation. Le rapport en poids du polymère de polyester au fluoropolymère est de 80 : 20 à 60 : 40. Lorsqu'elle est durcie, la composition de revêtement en poudre forme une seule couche de revêtement comprenant le polymère de polyester et le fluoropolymère.
