Anti-corrosion coatings containing thioamide groups

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 wherein the thioamide group is represented by the formula (I):

• —(C═S)—NR1R2 (I)
• wherein
• R1 and R2 each independently are 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 C atoms and aryl radical having 6 to 12 C atoms or radicals R1 and R2 together with the nitrogen atom may form a five- to 12-membered ring,

A process for producing coating materials for atmospheric corrosion control, comprising:

• first mixing a binder in dispersion in water with at least one compound comprising at least two thioamide groups (—(C═S)—NR1R2) and
• adding to the resultant mixture at least one pigment and/or filler, only after concluding the mixing of the binder in dispersion in water with the at least one compound comprising at least two thioamide groups.
