CA 2293625

This invention provides a method of bonding substantially non-fluorinated polymeric material to a fluoropolymer utilizing a bonding composition comprising primary or secondary di- or poly-amine and a melt- processable, substantantially non-fluorinated component. Multi-layer articles and composite constructions, including retroreflective sheeting and fuel line hoses, made of a fluoropolymer layer and a substantially non-fluorinated layer are also provided.

L'invention concerne un procédé permettant de lier un matériau polymère sensiblement non fluoré à un fluoropolymère au moyen d'une composition de liaison comprenant une di- ou poly-amine primaire ou secondaire et un composant sensiblement non fluoré se prêtant au traitement par fusion. L'invention concerne en outre des articles multicouches et des structures composites, notamment une feuille rétroréfléchissante et des tuyaux pour carburant, composés d'une couche de fluoropolymère et d'une couche sensiblement non fluorée.
