Title (EN) CORROSION INHIBITORS AND COATING COMPOSITIONS CONTAINING THE SAME
(FR) INHIBITEURS DE CORROSION ET COMPOSITIONS DE REVÊTEMENT LES CONTENANT
Abstract:
(EN) A corrosion inhibitor can include (a) an inorganic alkali and/or alkaline earth metal compound and (b) an aldehyde and/or ketone component comprising 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. The coating composition can be used in a multi-layer coating with additional coating layers. Methods of preparing coating compositions with corrosion inhibitors and substrates at least partially coating with such compositions are also included.
(FR) L'invention concerne un inhibiteur de corrosion pouvant comprendre (a) un composé inorganique de métal alcalin et/ou alcalino-terreux et (b) 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. La composition de revêtement peut être utilisée dans un revêtement multicouche présentant des couches de revêtement supplémentaires. L'invention concerne également des procédés de préparation de compositions de revêtement contenant des inhibiteurs de corrosion et des substrats au moins en partiellement revêtus par ces compositions.
