Abstract

L'invention concerne un procédé pour l'électrodéposition avec une composition de revêtement sur un support chargé négativement, plongé dans un bain de revêtement contenant une dispersion aqueuse de ladite composition de revêtement, ledit bain ayant une zone cathodique contenant ledit support et une zone anodique contenant une anode chargée, ledit support et ladite anode constituant des électrodes de charges opposées, les électrodes chargées étant maintenues en contact électrique l'une avec l'autre au moyen dudit bain, ledit bain comprenant un polymère filmogène cationique, un agent ionisant acide et un agent réticulant. Selon l'invention, a. On utilise l'acide phosphorique comme agent ionisant acide; b. On utilise comme polymère filmogène cationique un copolymère greffé ayant un squelette contenant des fonctions amine secondaire et/ou primaire, ledit copolymère greffé étant stabilisé dans la dispersion aqueuse par un phosphate des fonctions amine, ledit squelette étant polymérisé par greffage avec un copolymère hydrophobe dérivé d'époxyester, ledit copolymère hydrophobe ayant une concentration suffisamment élevée dans le copolymère greffé pour que le revêtement déposé sur le support ait une teneur en solides d'au moins environ 83 % et que la concentration d'acide phosphorique dans la composition de revêtement déposée ne dépasse pas environ 17,5 % de la concentration d'acide phosphorique dans le bain; et c. On utilise comme agent réticulant une composition non réactive dans le bain, mais réactive vis-à-vis dudit polymère filmogène à des températures élevées.The invention relates to a process for electrodeposition with a coating composition on a negatively charged support, immersed in a coating bath containing an aqueous dispersion of said coating composition, said bath having a cathode zone containing said support and an anode zone. containing a charged anode, said support and said anode constituting electrodes of opposite charges, the charged electrodes being maintained in electrical contact with each other by means of said bath, said bath comprising a cationic film-forming polymer, an acidic ionizing agent and a crosslinking agent. According to the invention, a. Phosphoric acid is used as an acid ionizing agent; b. As cationic film-forming polymer is used a graft copolymer having a backbone containing secondary and / or primary amine functions, said graft copolymer being stabilized in the aqueous dispersion with a phosphate of amine functions, said backbone being polymerized by grafting with a hydrophobic copolymer derived from epoxy ester, said hydrophobic copolymer having a sufficiently high concentration in the graft copolymer that the coating deposited on the support has a solids content of at least about 83% and the concentration of phosphoric acid in the coating composition deposited does not not exceed about 17.5% of the concentration of phosphoric acid in the bath; and c. As crosslinking agent is used a composition which is not reactive in the bath, but reactive with respect to said film-forming polymer at high temperatures.
