Abstract

L'invention concerne une composition pouvant être déposée par électrolyse comprenant: (a) une résine cationique contenant de l'hydrogène actif, qui peut être déposée par électrolyse sur une cathode; (b) un polyisocyanate coiffé, servant d'agent de durcissement; et (c) un catalyseur contenant un organo-étain. L'amélioration consiste à ajouter à la composition destinée à former un revêtement, un composé non miscible à l'eau portant un ou plusieurs groupes acides et ayant une chaîne hydrocarbonée avec au moins 5 atomes de carbone. La composition présente un comportement amélioré lors du durcissement et un aspect amélioré après le durcissement, lorsqu'il est déposé par électrolyse sur des substrats conducteurs.
