Patent ID: 8268404

Claim:
A method comprising applying a corrosion control coat to a metallic surface, the method comprising treating the metallic surface with a preparation comprising a binder system (A), a component (B) selected from the group consisting of a finely divided filler, a pigment and a dye, and a polymeric corrosion preventative, wherein said polymeric corrosion preventative is a copolymer (C) obtained by polymerizing monomeric building blocks: (C1) 5% to 60% by weight of at least one monoethylenically unsaturated monomer which comprises at least one nitrile group, (C2) 10% to 70% by weight of at least one monoethylenically unsaturated monomer which comprises at least one acid group, (C3) 20% to 80% by weight of at least one monoethylenically unsaturated aromatic hydrocarbon, and (C4) optionally 0% to 25% by weight of at least one non-ethylenically unsaturated monomer, the amount being based in each case on the total amount of all monomeric structural units in the copolymer; and drying and curing the polymeric corrosion preventative under atmospheric conditions.
