Title (EN) COATING COMPOSITION CONTAINING POLYESTER POLYMERS WITH TERMINAL CARBAMATE GROUPS AND POLYMERIC POLYOL DERIVED FROM ETHYLENICALLY UNSATURATED MONOMERS
(FR) COMPOSITION DE REVETEMENT CONTENANT DES POLYMERES POLYESTERS POURVUS DE GROUPES CARBAMATE TERMINAUX ET D'UN POLYOL POLYMERE DERIVE DE MONOMERES ETHYLENIQUEMENT INSATURES
Abstract:
(EN) An adherent film-forming composition comprising a carbamate-functional polyester polymer or oligomer, a hydroxy functional polymer derived from ethylenically unsaturated monomers and an aminoplast cross-linking agent is disclosed. The coating composition can be used to produce clear coats in composite color plus clear coatings exhibiting good levels of acid etch resistance as well as high intercoat adhesion. Also disclosed are a method of applying a composite color plus clear coating to a substrate and the coated article prepared by such a method.
(FR) L'invention se rapporte à une composition filmogène adhésive comprenant un polymère ou oligomère de polyester à fonctionnalité carbamate, un polymère à fonctionnalité hydroxy dérivé de monomères éthyléniquement insaturés et un agent de réticulation d'aminoplaste. La composition de revêtement peut être utilisée pour produire des revêtements transparents dans des revêtements composites couleur et transparents présentant une bonne résistance à l'attaque aux acides ainsi qu'une forte adhésion entre les revêtements. L'invention se rapporte également à un procédé d'application sur un substrat d'un revêtement composite couleur et transparent et à l'article recouvert préparé par ce procédé.
