Abstract
La presente invencion se refiere a una composicion de tratamiento de superficie líquida acuosa que tiene un valor de pH no mayor de 6.5 y que contiene iones de ácido fosforico, iones de ácido fosforico condensado, un agente oxidante, un polímero soluble en agua que consiste en, excepto para los grupos terminales, de unidades poliméricas expresadas por la formula (I), en una relacion de peso de 0.1 a 30: 0.1 a 10:0.1 a 10:0.1 a 20 respectivamente, cuando se pone en contacto con una superficie de metal aluminífero, rápidamente forma sobre la superficie un revestimiento de conversion que tiene buena resistencia a la corrosion y adhesion para revestimientos orgánicos posteriormente aplicados como puede ser pintura y se daña con menos facilidad por esfuerzos mecánicos que los revestimientos de conversion de la técnica anterior.
