Patent ID: 7981954

Claim:
A method for the control of atmospheric corrosion of a metallic surface comprising coating the metallic surface with a coating material comprising at least one compound having at least one thioamide group of formula (I): R 4 n —R 3 —(C═S)NR 1 R 2 (I) wherein R 1 and R 2 are independently selected from the group consisting of H, linear or branched, optionally substituted alkyl radical having 1 to 20 C atoms, cycloalkyl radical having 3 to 12 atoms and aryl radical having 6 to 12 C atoms or radicals R 1 and R 2 together with the nitrogen atom may form a five- to 12-membered ring; n is a natural number from 1 to 5; R 3 is a hydrocarbon radical of 1 to 30 C atoms having a valency of n+1; R 4 is at least one functional group selected from the group consisting of an ether group, —OH and —NH 2 wherein the coating material has a thickness of at least 40 μm.
