Corrosion control is a significant problem for military equipment. Many surface treatment materials currently in use on items of military or aerospace materiel contain chrorniumVI as a component, a source of significant human health and environmental hazard. The formulation under evaluation contains no chromium. Most of the proposed components are of low to moderate toxicity and are not a significant concern. Two of the formulation components are associated with some cancer hazard-2-mercaptobenzothiazole and formaldehyde, but both find wide spread use in industry and additional investigation is not required for this project.
