Corrosion inhibitor composition applicable for aluminium and steel protection and procedure
Abstract
A process for protecting an aluminium or steel substrate against atmospheric corrosion by applying a coating of a corrosion-inhibiting material to the surface of the substrate. The corrosion-inhibiting composition is for application to the metal substrate and is used in connection with a paint. The synthesis of the composition is disclosed. The corrosion-inhibiting composition includes a protective material selected from a group consisting of di-mercapto and poly-mercapto compounds and their derivatives, wherein the protective material has a limited solubility in water.
