DEVELOPMENT OF A RUST-REMOVING CORROSION PREVENTATIVE

摘要

Removable corrosion preventives were developed that, when applied to rusted steel or iron surfaces, remove or adsorb the rust during storage and prevent further deterioration. It was necessary to use sera polar wax-base materials in order to provide sufficient rust-removing activity. In all of the formulations, fatty amides are used as the wax-base. The rust-removing activity was supplied by materials of an acidic nature, p-toluene sulfonic acid or salicylic acid, or by chelating agents of the p-dike tone class. The diamide of oleic acid and diethylenetriamine was added as a corrosion inhibitor. The formulations are effective in removing light rust films and pro-vide protection against rerusting under inside storage conditions. (U) (Author)
