CA 2595969
The invention relates to a method for applying integrated pre-treatment layers with a thickness of between 1 and 25 µm to metallic surfaces, especially the surfaces of strip metals, by treatment with a composition containing at least one binding agent, a cross-linking agent, a fine-particle inorganic filler, and a dicarboxylic acid olefin copolymer. The invention also relates to metallic moulded bodies provided with one such integrated pre-treatment layer, and a formulation for carrying out the method.
L'invention concerne un procédé permettant d'appliquer des couches de traitement préalable intégrées, d'une épaisseur allant de 1 à 25 µm, sur des surfaces métalliques, notamment des surfaces de feuillards, par traitement avec une préparation contenant au moins un liant, un agent de réticulation, une charge inorganique à fines particules, ainsi qu'un copolymère à base d'acide dicarboxylique et d'oléfine. L'invention concerne également des corps moulés munis de la couche de traitement préalable intégrée du type selon l'invention, ainsi qu'une formulation pour mettre ledit procédé en oeuvre.
