Abstract

La présente invention décrit un procédé qui consiste à chauffer un mélange aqueux composé d'un fluoroacide tel que H2TiF6 et d'un oxyde, d'un hydroxyde et/ou d'un carbonate tel qu'un dioxyde de silicium afin d'obtenir un mélange transparent capable de résister à long terme à la formation de toute phase solide, même lorsque la phase d'oxyde, d'hydroxyde ou de carbonate, avant le chauffage, était un solide dispersé dont les particules étaient suffisamment grandes pour diffuser la lumière et rendre le mélange avant le chauffage trouble. Le mélange transparent produit par chauffage peut être soit mélangé avec des polymères solubles et/ou dispersibles dans l'eau, par exemple avec des polymères dispersés de l'éther de diglycidyle de bisphénole-A ou un polymère d'acide acrylique, soit avec du chrome soluble hexavalent et/ou trivalent, afin de produire une composition capable d'améliorer la résistance à la corrosion des métaux ainsi traités, en particulier si une peinture a été appliquée après traitement. Une autre composition qui améliore la résistance à la corrosion des métaux à la suite d'un contact avec lesdits métaux consiste en une soulution aqueuse d'un mélange de: (A') un polymère soluble ou dispersible dans l'eau doté d'au moins une molécule du groupe -OH par polymère sélectionné parmi le groupe composé d'alcool polyvinylique, de polyéthylène glycol, d'amidon modifié et de mélanges d'amidon, et (B') polymères et copolymères d'acide acrylique et méthacrylique et leurs sels.
