ABSTRACT:
Metal substrates, and particularly ferrous metal substrates, are now protected by having on their surface composite coatings wherein the base coating comprises a water-insoluble phosphatized coating from an organic phosphatizing composition. Over the phosphatized base coating there is then deposited a topcoating that is typically a paint topcoating. However, a rinse coating, such as a chromic acid solution, may be used on the base coating prior to a paint coating. A highly desirable adherent, corrosion-resistant and water-insoluble composite coating thereby protects the substrate metal.
