Abstract

Un proceso para incrementar la hidrofilicidad de una superficie solida sobre la cual el agua líquida pura tiene, bajo presion atmosférica normal y unatemperatura que oscila entre 18 y 23*C, un ángulo de contacto inicial de por lo menos 5*, caracterizado por comprender los pasos de: I) formacionsobre dicha superficie solida de un recubrimiento de una composicion líquida de hidrofilizacion que comprende agua y cierta concentracion de un componente(A) seleccionado del grupo integrado por moléculasde polímeros orgánicos disueltas, establemente dispersas, o disueltas y establemente dispersas quecontienen porciones -SO3M, en donde M representa hidrogeno, un cation monovalente, o una fraccion monovalente de un cation con una valencia de dos o más, yII) secado del recubrimiento de la composicion líquida formado en el paso (I) a los efectos de obtener una superficie solida modificada sobre la cual al menosparte de los polímeros que contienen porciones -SO3M que se encontraban en dicha composicion preparada en el paso (I) permanecen enlazados, en tanto el agualíquida pura tiene bajo presion atmosférica y a una temperatura normal un ángulo de contacto inicial sobre dicha superficie solida modificada inferior a suángulo de contacto sobre lasuperficie solida recubierta en el paso (I). Dicho proceso de hidrofilizacion especialmente efectivo para sustratos solidos,particularmente aquellos sustratos de aluminio a los que se les ha aplicado un recubrimiento de conversion, está integrado por una mezcla líquida de agua,moléculas de polímeros orgánicos que comprenden porciones sulfonil/sulfonato, y preferiblemente además una sustancia que se prepara mezclando con ácidofosforico acuoso al menos un metal, un oxido de metal o un hidroxido de metal a los efectos de obtener una mezcla líquida transparente. El tratamientolíquido preferentemente tiene un pH prácticamente neutro y es aplicado a un sustrato y secado por exposicion al calor. La composicion comprende al componente(A) y (B) aproximadamente entre 0.5 y 25 partes por mil de un componente (B) integrado por una o más sustancias disueltas que han sido seleccionadas del
