Abstract
L'invention porte sur une composition se prêtant à un processus d'électrodéposition et comprenant: a), une résine cationique non-gélifiée dérivée d'un polyépoxide, les molécules de cette résine comprenant des groupes de sel cationique et des groupes à hydrogène actif, sélectionnés à partir de groupes hydroxyl aliphatiques et d'amines primaire et secondaire, et se présentant comme composant distinct; b), un agent de traitement entièrement bloqué de polyisocyanate ne contenant pratiquement pas de groupes libres d'isocyanate. Cette composition se prêtant à une électrodéposition contient de 0,02 à 1,0 milliéquivalents de groupes phénoliques hydroxyl par gramme de matières sèches de résine environ et de 0,1 à 2,0 milliéquivalents de groupes d'ester bêta-hydroxy par gramme de matières sèches de résine environ. Cette composition assure une excellente tenue à la corrosion lorsque elle est déposée par électrolyse sur des substrats d'acier tandis que sa préparation n'exige pas la présence de plomb pas plus qu'elle n'utilise le rinçage à l'acide chromique pour le prétraitement du substrat d'acier avant de procéder à l'électrodéposition.
