Abstract : DoD-P-15328 wash primer is a unique coating that passivates metal surfaces against corrosion and enhances adhesion of primers/topcoats. However, the chromate and high-solvent content subject it to strict Environmental Protection Agency (EPA) regulations. This report evaluated waterborne (WB) polymers and coating systems as in earlier investigations. Laboratory evaluations revealed a film-softening effect when topcoated with solvent-type primers due to trapped solvents in the wash primer. Wash primers formulated with VOC-exempt solvents are being tested.
