The patent application describes a method for obtaining a water-based coating forming a dispersion (emulsion), with anti-corrosion properties for metallic substrates (iron and its alloys (steel), aluminum and its alloys, magnesium and its alloys). It also protects the coating obtained by this method and the uses of this system.

The present invention is directed to a method for producing a coating system providing corrosion-protective properties when applied to metal surfaces, particularly in the form of a water-based (waterborne) composition, preferably in the form of a dispersion (i.e. emulsion or latex, respectively), as well as to coating system thus produced and to its various applications. The resulting coating system provides superior properties with respect to corrosion protection, on the one hand, and adhesion to metal surfaces, on the other hand, while at the same time being environmentally compatible and easy to use and to apply and being producible in an economic way.
