Abstract

An anti-corrosive coating compound with: component I: cathodically active metal particles and component II: binder in the presence of water. In order to improve the service life of the coating compound, it is provided that an oxygen compound or a mixture of oxygen compounds of the subgroup elements, namely ammonium, alkaline or earth alkaline salts of an acid of a transition metal, is added as component III. The invention further relates to a method for producing an anti-corrosive coating compound, a workpiece coated with the anti-corrosive coating compound and the use of an oxygen compound or a mixture of oxygen compounds of the subgroup elements in an anti-corrosive coating compound.
