| titleOfInvention | METHOD FOR OBTAINING A STABLE AQUEOUS COMPOSITION FOR COATING METALLIC SURFACES. |
| abstract | 1. Method for obtaining a stable aqueous composition to coat metal surfaces, especially iron, zinc and aluminum surfaces, in order to increase the resistance to corrosion and the adhesion properties of the paint on them, characterized in that they are established the following reaction steps; 1) the formation of an aqueous solution of chromium trioxide and phosphoric acid; 2) the reduction of about 40 to 60% of hexavalent chromium to trivalent chromium under conditions suitable to completely dissolve all reaction products; 3) add the polyacrylic acid to the reduced chromium solution under suitable conditions to ensure complete interaction of the reactants present; and 4) adding the acrylic emulsion polymer to the solution of partially reduced chromium and polyacrylic acid. |
