Abstract: The invention relates to an anti-corrosive coating agent for metal workpieces. For the purpose of good cathodic corrosion prevention, the anti-corrosive coating agent comprises an organic binder having a silicon-organic compound and particulate metal. The workpiece having an anti-corrosive coating is characterized in that the anti-corrosive coating comprises an organic binder having a silicon-organic compound and particulate metal. The method for producing an anti-corrosive coating on a workpiece is characterized by applying, in liquid form, a first coating, comprising an organic binder having a silicon-organic compound and particulate metal as the anti-corrosive coating, and then applying a second coating the composition of which preferably differs from that of the anti-corrosive coating.

Abstract: A mixer system, for preparing two-component water-dilutable coating agents, includes a plurality of substantially water-free base colors and a pigment-free aqueous component. One or more of the base colors can be mixed together with a suitable amount of the aqueous component to match a preexisting coating color on a substrate to be repaired. Each of the base colors includes a pigment, an organic solvent and a first binder. The pigment-free aqueous component includes water and a second binder. The second binder is a polymer made from a mixture which includes a monomer component, an initiator, and an aqueous dispersion of a polyurethane resin. Cured coatings which are prepared from compositions using the disclosed mixer system exhibit improved condensation resistance, as compared with previously known coatings.
