Numerous proprietary and developmental organic coatings were screened for their relative corrosion protection of Mg sheet alloy. Superior primers and systems were more fully evaluated for their mechanical properties as well as corrosion protection. Finish evaluations were conducted on FS-IH Mg alloy. The coatings included vinyls and modified vinyls, alkyd and modified alkyd finishes, acrylic and modified acrylic finishes, HAE refractory coatings, and miscellaneous vehicles. The air-dry vinyl systems offered optimum protection in the systems tested. Developmental data and discussions of Mg corrosion inhibitors and galvanic-cell test methods are included.
