Abstract

L'invention consiste à former sur une surface métallique un revêtement en résine, au moyen d'une composition de résine aqueuse à auto-déposition, contenant un agent oxydant, un acide et une résine soluble ou dispersible dans l'eau, à fonction carboxyle et/ou hydroxyle, et éventuellement, des ions métalliques. Le revêtement ainsi obtenu, alors qu'il est encore à l'état non durci, est soumis à un post-traitement avec une solution aqueuse contenant entre 0,5 et 5,0 g/L d'une amine et entre 10 et 100 g/l (solides) de molécules de résine aminique solubles dans l'eau, portant au moins deux groupes alcoxyméthylamino, méthylolamino et/ou imino. Le revêtement est ensuite séché et durci. Ce procédé permet d'obtenir sur le métal un revêtement hautement anticorrosion, et contrairement à un procédé analogue dans lequel la solution de post-traitement contient une résine aminique mais pas d'amine, cette solution de post-traitement reste stable et assure une efficacité de revêtement continue, de haute qualité, même après qu'on ait traité une surface métallique très importante par volume unitaire de solution de post-traitement.
