Abstract

Una composicion y un procedimiento adecuados para el tratamiento de superficies metálicas, donde la composicion comprende sílice, uno o másorgano-fosfonatos (u organo-fosfonatos metálicos) y/o uno o más organo-fosfatos (u organo-fosfatos metálicos),conjuntamente con un excipiente. La composicionpuede ser aplicada a una superficie metálica para aumentar la resistencia del metal a la corrosion y/o para aumentar la adherencia de recubrimientosadicionales al metal tratado. En donde la sílice tieneun tamano de partícula promedio comprendido entre 1 y 200 nm. El proceso para tratar superficiesmetálicas consiste en: a) Preparar dicha composicion dispersando la sílice en agua y mezclando el componente organo-fosfonato u organo-fosfato enladisper sion, b) Aplicar dicha composicion a una superficie metálica y c) Dejar o hacer secar la composicion así aplicada para formar un recubrimiento adherentesobre dicha superficie metálica.A composition and method suitable for the treatment of metal surfaces, where the composition comprises silica, one or more organophosphonates (or metal organophosphonates) and / or one or more organo phosphates (or metal organo phosphates), together with an excipient The composition can be applied to a metal surface to increase the resistance of the metal to corrosion and / or to increase the adhesion of additional coatings to the treated metal. Where the silica has an average particle size between 1 and 200 nm. The process for treating metal surfaces consists of: a) Preparing said composition by dispersing the silica in water and mixing the organo-phosphonate or organo-phosphate component enladisper sion, b) Applying said composition to a metal surface and c) Letting or drying the composition like this applied to form an adherent coating on said metal surface.
