Evaluation of Water-Borne Lead and Chromium Free Anti-Corrosive Primers

摘要

US AMERADCOM is striving to replace primers used on Army Equipment with low VOC coatings in order to meet air quality regulations and to eliminate lead and Chromium VI. 35 water-borne, lead and chromium-free formulations and proprietary primers were evaluated. One formulation and one proprietary primer are almost equal to TT-P-1757 in corrosion resistance. Another formulation and two proprietary primers are acceptable with minor modifications. Six other formulations and one proprietary primer are acceptable for use on aluminum but not on steel.
