The invention provides a coating composition for use with metallic substrates that provides desirable levels of adhesion to metal, sandability without the production of harmful dust, corrosion resistance, and recoatability. The coating composition of the invention comprises a polyurethane film-forming component, and a corrosion protection component present in the composition in an amount effective in minimizing corrosion and adhesion loss of the coating at the substrate. A cured film of the coating applied to metallic substrates, previously coated substrates, as well as plastic substrates has improved corrosion resistance following Salt Spray Cabinet exposure. |
