Abstract
El fenomeno de "aplicaciones" (efectos superficiales) después de la pintura electroforética sobre revestimientos de conversion de fosfatos pasivados con composiciones de pasivacion que contienen cromo hexavelente se puede evitar o reducir manteniendo la superficie que se está tratando humeda constantemente desde el tiempo en que se reviste por conversion hasta que se pinte electroforéticamente, precediendo el paso de pasivacion mediante un tratamiento con un composicion de tratamiento líquida acuosa que comprende por lo menos uno de los siguientes componentes: (A) un polímero soluble en agua y/o dispersible en agua con un peso molecular promedio en peso de por lo menos 500; (B) ácidos fluorometálicos y aniones de los mismos, las moléculas de los cuales consisten de (i) por lo menos un átomo de boro, silicio, zirconio, hierro, aluminio, o titanio, (ii) por lo menos cuatro átomos de fluor y opcionalmente (iii) uno o más átomos de oxígeno, hidrogeno o ambos; (C) sales de zirconio del ácido teraacético de etilendiamina; y (D) carboxilatos y carbonatos de zirconilo de amonio y metal alcalino; o reemplazando la composicion de pasivacion que contiene cromo por una composicion de tratamiento líquido acuosa del mismo tipo que se describe en lo que antecede.
