| description | The present invention relates to an aqueous composition based on phosphates, aluminum ions and other metal ions, in particular manganese ions and zinc ions, as well as silicates, siloxanes or silanes, for providing anticorrosive coatings on metal surfaces, in particular for the electrical insulation of grain-oriented electrical steel strip. For the desired functionality, the compositions according to the invention contain the constituents mentioned in a prescribed ratio to one another. The invention also relates to a method for coating the surface of a metallic workpiece by using the aqueous compositions, wherein the method produces outstanding results, in particular on grain-oriented electrical steel strip, with regard to corrosion protection and adherence. |
