CORROSION INHIBITIVE PERFORMANCE OF SOME COMMERCIAL WATER-REDUCIBLE, NONTOXIC PRIMERS

Recent laws and regulations limiting the use of various materials in paint are requiring users and manufacturers of corrosion inhibitive coatings to make use of relatively untried formulations. This study is an examination of the corrosion inhibitive performance of five water-reducible, non-toxic primers compared to two standard solvent-borne primers. The corrosion tests used were Salt Fog Cabinets, Blister Cabinets, Kesternich Cabinet, Cleveland Condensation Tester, and outdoor exposures. The results indicate that water-borne, non-toxic primers are generally not equivalent in performance to the solvent-borne, chromate pigmented primers tested.
