Title
(EN) ELECTRODEPOSITABLE COATING COMPOSITIONS
(FR) COMPOSITIONS DE REVÊTEMENT ÉLECTRODÉPOSABLES
Abstract
(EN) The present disclosure is directed to an electrodepositable coating composition comprising (a) a hydroxyl-functional addition polymer comprising constitutional units, at least 70% of which comprise formula (I) wherein each R1 is independently one of hydrogen, an alkyl group, a substituted alkyl group, a cycloalkyl group, a substituted cycloalkyl group, an alkylcycloalkyl group, a substituted alkylcycloalkyl group, a cycloalkylalkyl group, a substituted cycloalkylalkyl group, an aryl group, a substituted aryl group, an alkylaryl group, a substituted alkylaryl group, a cycloalkylaryl group, a substituted cycloalkylaryl group, an arylalkyl group, a substituted arylalkyl group, an arylcycloalkyl group, or a substituted arylcycloalkyl group, and the % based upon the total constitutional units of the hydroxyl-functional addition polymer; (b) an active hydrogen-containing, ionic salt group-containing film-forming polymer; (c) a curing agent; and (d) a curing catalyst.
(FR) La présente divulgation concerne une composition de revêtement électrodéposable comprenant les éléments suivants : (a) un polymère à ajout de fonction hydroxyle comprenant des unités constitutives, dont au moins 70 % comprennent la formule (I) dans laquelle chaque R1 est indépendamment un élément parmi l'hydrogène, un groupe alkyle, un groupe alkyle substitué, un groupe cycloalkyle, un groupe cycloalkyle substitué, un groupe alkylcycloalkyle, un groupe alkylcycloalkyle substitué, un groupe cycloalkylalkyle, un groupe cycloalkylalkyle substitué, un groupe aryle, un groupe aryle substitué, un groupe alkylaryle, un groupe alkylaryle substitué, un groupe cycloalkylaryle, un groupe cycloalkylaryle substitué, un groupe arylalkyle, un groupe arylalkyle substitué, un groupe arylcycloalkyle ou un groupe arylcycloalkyle substitué, et le % par rapport aux unités constitutives totales du polymère à ajout de fonction hydroxyle ; (b) un polymère filmogène contenant de l'hydrogène actif et des groupes de sels ioniques ; (c) un agent de durcissement ; et (d) un catalyseur de durcissement.
