Solvent based inorganic zinc rich primers have performed well when exposed to a salt air environment, such as is found at Kennedy Space Center (KSC), Florida. Laboratory and field testing have been performed on several new low volatile organic content (VOC) inorganic zinc rich primers, such as high solids solvent based and water-based formulations, applied to mild steel. These new materials are important due to stricter environmental regulations that are being proposed. Electrochemical laboratory test results, from both dc and ac methods, will be compared to preliminary results of exposure at a beach corrosion test site located along the Atlantic Ocean at KSC.
