Abstract (en)

Compositions for protecting metals, which contain a mixture consisting of stearic acid, dicyclohexylamine and an azole derivative, and more particularly compositions containing from 0.8 to 1.5 g/l of 1-phenyl-5-mercaptotetrazole and from 0.005 to 0.01 g/l of the stearic acid:dicyclohexylamine mixture in the molar ratio of 1:1, in solution in water, and process for its preparation, and methods of protecting metals by employing the said compositions.
