Removable corrosion preventatives were developed that, when applied to rusted steel or iron surfaces, remove or adsorb the rust during storage and prevent further eeterioration. It was necessary to use semipolar wax-base materials in order to provide sufficient rust-removing activity. Fatty amides were used as the was base in all of the formulations. 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 beta-diketone class. The diamide of oleic acid and diethylenetriamine was added as a corrosion inhibitor. The formulations are effective in removing light rust films, and they provide protection against rerusting under inside storage conditions. Author
