Title (EN) USE OF BLOCK COPOLYMERS BEARING PHOSPHATE AND/OR PHOSPHONATE FUNCTIONS AS ADHESION PROMOTERS OR AS PROTECTING AGENTS AGAINST THE CORROSION OF A METALLIC SURFACE
(FR) UTILISATION DE COPOLYMERES A BLOCS PORTANT DES FONCTIONS PHOSPHATES ET/OU PHOSPHONATES COMME PROMOTEURS D'ADHESION OU COMME AGENTS DE PROTECTION CONTRE LA CORROSION D'UNE SURFACE METALLIQUE
Abstract: front page image
(EN)The invention relates to the use of a block copolymer having at least one block that comprises phosphate and/or phosphonate functions in order to produce a deposit on a metallic surface, such as a steel or aluminium surface, which can be used, for example, to improve the effectiveness of the subsequent application of a film-forming composition on the thus altered surface or to protect the metallic surface against corrosion. The invention also relates to a method of applying paint or mastic compositions to a metallic surface, which involves the above-mentioned inventive use of said block copolymers, and the coated metallic materials that can be produced using said application method.
(FR)La présente invention concerne l'utilisation d'un copolymère à blocs, dont au moins un bloc comporte des fonctions phosphates et/ou phosphonates, pour réaliser sur une surface métallique telle qu'une surface d'acier ou d'aluminium, un dépôt notamment utilisable pour améliorer l'efficacité de l'application ultérieure d'une composition filmogène sur la surface ainsi modifiée ou pour protéger ladite surface métallique contre la corrosion.L'invention concerne également un procédé d'application de compositions de peintures ou de mastics sur une surface métallique, mettant à profit ce type d'utilisation, ainsi que les matériaux métalliques revêtus susceptibles d'être obtenus selon un tel procédé d'application.
