Title
(EN) MULTILAYER NON-STICK COATING
(FR) REVETEMENT ANTI-ADHESIF MULTICOUCHE
Abstract
(EN)
A non-stick coating formed on a substrate comprising a primer composition and a topcoat composition, wherein the primer composition is between the topcoat composition and substrate. The primer composition comprises at least one heat resistant adhesion promoter. The topcoat composition comprises at least one fluorocarbon resin and at least one heat resistant adhesion promoter other than a fluoropolymer that may be the same or different than the adhesion promoter of the primer composition. There are inorganic inert particles with an average particle size of at least about 10 micrometers contained in the primer composition. The invention includes the method for forming the coating.
(FR)
L'invention concerne un revêtement anti-adhésif formé sur un substrat, qui comprend une couche primaire et une couche de finition. La couche primaire est placée entre la couche de finition et le substrat. La couche primaire comprend au moins un promoteur d'adhérence thermorésistant. La couche de finition comprend au moins une résine fluorocarbonée et au moins un promoteur d'adhérence thermorésistant, autre qu'un polymère fluoré, qui peut être identique ou différent du promoteur d'adhérence de la couche primaire. La couche primaire contient des particules inorganiques inertes présentant une granulométrie moyenne d'au moins environ 10 micromètres. On décrit le procédé de réalisation du revêtement de l'invention.
