Title (EN) CORROSION INHIBITORS AND COATING COMPOSITIONS CONTAINING THE SAME
(FR) INHIBITEURS DE CORROSION ET COMPOSITIONS DE REVÊTEMENT LES CONTENANT
Abstract:
(EN) A method of applying a coating to a surface of a substrate includes: (1) applying a coating composition to at least a portion of a metal surface of a substrate; and (2) curing the coating composition to form a coating over at least a portion of the surface of the substrate. The coating composition includes: (i) a film forming resin; and (ii) a corrosion inhibitor that formed from (a) an inorganic alkali and/or alkaline earth metal compound and (b) an aldehyde and/or ketone component having at least one aromatic ring comprising a ketone and/or aldehyde group and at least one pendant group represented by -OR1. Each R1 is independently selected from hydrogen, an alkyl group, or an aryl group.
(FR) Un procédé d'application d'un revêtement sur une surface d'un substrat comprend: (1) l'application d'une composition de revêtement sur au moins une partie d'une surface métallique d'un substrat; et (2) le durcissement de la composition de revêtement pour former un revêtement sur au moins une partie de la surface du substrat. La composition de revêtement comprend: (i) une résine filmogène; et (ii) un inhibiteur de corrosion qui est constitué : (a) d'un composé inorganique alacalin et/ou d'un composé alcalino-terreux et (b) d'un constituant de type aldéhyde et/ou cétone comprenant au moins un cycle aromatique comprenant un groupe cétone et/ou aldéhyde et au moins un groupe latéral représenté par -OR1. Chaque R1 est choisi, indépendamment, parmi hydrogène, un groupe alkyle ou un groupe aryle.
