Claim 0:
1. Coating system, more particularly corrosion control coating system, for generating cathodic corrosion protection on a metallic substrate, comprising at least two compositions,
characterized in that the coating system comprises:
(a) a first composition for forming a first layer in the form of an anhydrous cathodic corrosion control composition configured to crosslink on exposure to moisture at temperatures of less than 100° C.,
wherein the first cathodic corrosion control composition comprises at least one non-aqueous solvent, and

(b) a second composition for forming a second layer in the form of an aqueous-based coating composition;
wherein the second composition comprises hydrophilic, inorganic, or organic, polymer compounds;
wherein the second composition comprises ionic constituents in amounts of 0.1 to 5 wt %, based on the second composition, and/or
wherein the hydrophilic, inorganic or organic polymeric compound comprises ionic fractions; and
wherein the coating system is configured for curing at temperatures of 20° C. to 100° C.
