METHOD OF GIVING CORROSIONPROOF COATING ONTO METALLIC BASE MATERIAL AND ARTICLE CONSISTING OF SAID CORROSIONPROOF COATING BASE MATERIAL

摘要

This invention is directed to the use of particularly defined epoxy-amine compositions as a protective coating on metals which are exposed to a high temperature, corrosive environment. The metal may be that employed in motor vehicle exhaust system components, such as mufflers and tailpipes. The epoxy-amine compositions comprises epoxy resin component, aromatic amine component, optionally, acid component selected from polycarboxylic acid and anhydrides thereof and optionally, polyol component.
