ABSTRACT:
A method for the inhibition of corrosion of metals involves treatment of the metal surface with a polyester having a functional terminal group such as an amine. The polyester may be used together with other corrosion inhibitors, a useful combination being the polyester together with a hydroxy-oxime. The corrosion inhibiting material may be incorporated into a surface coating composition such as paint which is then applied to the metal surface.
