A composite article is provided which includes a blend component (12) having first and second surfaces and a subtantially non-fluorinated polymer component adhered to the first surface of the blend component, wherein the substantially non-fluorinated polymer component has an exposed surface. The blend component (12) inclu des a first hydrogen containing fluoropolymer; and a substantially non-fluorinated polymer having one or more pendant primary or secondary amine groups. Increased adhesion is observed by a peel strength value between the blend component and the substantially non-fluorinated polymer (18) component when compared to a peel strength value between a component consisting of a fluoropolymer and a component consisting of a substantially non-fluorinated polymer having pendant primary or secondary amine groups.
L'invention concerne un article composite qui comprend un composant mixte (12) présentant une première et une seconde surface, et un composant polymère sensiblement non fluoré collé sur la première surface du composant mixte et présentant une surface exposée. Le composant mixte (12) comprend un premier polymère fluoré contenant de l'hydrogène, et un polymère sensiblement non fluoré comportant un ou plusieurs groupes amines primaires ou secondaires libres. On observe une adhésion accrue quand on compare la résistance au pelage entre le composant mixte et le composant polymère sensiblement non fluoré (18) avec la résistance au pelage entre un composant constitué d'un polymère fluoré et un composant constitué d'un polymère sensiblement non fluoré comportant des groupes amines primaires ou secondaires libres.
