Advanced Primer and Superhydrophobic Topcoat for Corrosion Resistance and Leachate Impedance

Abstract

A series of coatings were developed and evaluated for their use on galvanized metal to inhibit corrosion and mitigate zinc leaching from the metal substrate. A zinc free, aluminum based inorganic primer was developed and tested. Additionally, a novel process was used to integrate superhydrophobic diatomaceous earth (SHDE) into current MIL-SPEC coatings to enhance their corrosion resistance and convert the coating to one with volumetric superhydrophobic properties. The coatings were evaluated with a variety of laboratory tests and long term in-situ exposures. This report describes the testing and evaluation of both coatings, lessons learned, and recommendations.
