Abstract

Method for obtaining on finished metallic surfaces with synthetic resins of ceramic type, essentially to protect, in decorative form, said surfaces against external agents of corrosión and mechanical damage characterized in that for its realization i understand, to submit the metal surface to a treatment of primer, previous degreasing in hot under the action of the vapor of usual solvents, whose primer comprises a thinner for synthetic resins in a proportion of 20 to 25% and, once the primer is dry, subject the surface thus prepared to a second treatment with a synthetic paint of the oven-dried type, formed by a white base pigment diluted 15-20% in an organic diluent and/or synthetic retardant normal in the art, allowing the assembly to dry in the open air and then forming an enamel and successive diffusive, without intermediate drying between both, by treatment of the surface by of the aforementioned base coating with respective varnish compositions previously obtained with 10 to 20% of a concentrated dye, according to the selected color and 10 to 15% of the synthetic diluent for the enameling, respectively 20-30% thereof for the dyeing, per 100 parts by weight of the varnish, and finally, once the treated surface is air dried until the solvent is removed, treat the resulting product thermally at temperatures of 120º-140º c.
