Wash Primer Replacement Based on the Superprimer Technology

Abstract

A replacement for the wash primer that meets the military specification DoD-P-15328D has been developed. It is water-borne, contains no hexavalent chromium, has very low VOC and contains no HAPs. It has been tested on cold-rolled steel and the aluminum alloy AA7075-T6. On both metals the proposed replacement exceeds the performance of the DoD-P-15328D primers in various tests, including SST, EIS and CCT. Adhesion to primers is also improved by the new wash primer. The application process is simple and the metal pretreatment is not critical.
