ABSTRACT:
Corrosion of metals and cathodic disbondment of coated metals, especially steel, iron and aluminum, are reduced by coating the metals with a composition of 1-70% by weight of a modified polyolefin and 30-99% by weight of metallic zinc. The modified polyolefin is obtained by grafting a polyolefin with an ethylenically unsaturated aliphatic carboxylic acid or derivative thereof, the polyolefin being a homopolymer or copolymer of a C.sub.2 -C.sub.12 hydrocarbon alpha-olefin.
