The invention relates to a corrosion inhibiting composition, comprising at least:
A) a carrier of an oily or waxy type;
B) active components comprising at least
B1) a corrosion-inhibitor of the azole-type; and
B2) a co-corrosion-inhibitor, selected from the group consisting of
(a) fatty acids having 6-24 carbon atoms, aromatic acids and naphthenic acids, which acids have the free acid form or the salt form;
(b) imidazoline derivatives having an C6-24 alkyl moiety; and
(c) C6-24 alkylsuccinic anhydride compounds; as well as a mixture of compounds defined under (a), (b) and/or (c); and
C) optionally a compound selected from the group consisting of
C1) a water repellent;
C2) a synthetic ester derived from a C1-10 alcohol with 1-12 hydroxyl groups and C6-24 fatty acids; and
C3) a C6-18 alcohol as well as a mixture of compounds defined under C1), C2) and/or C3).
Such a composition is suitable for application on elongated objects of steel, covered with a coating of a material having an electrode potential, exceeding the electrode potential of steel or having a rate of corrosion, which is less than the rate of corrosion of steel. Further the invention relates to elongated objects of steel, in particular steel cords treated with a corrosion inhibiting composition according to the invention. Another object of the invention is a process for treating elongated objects of steel with the corrosion inhibiting composition according to the invention. Rubber articles, which contain elongated objects of steel like steel cord, treated with the above-mentioned composition do also fall within the scope of the invention.
