Abstract: 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.

Abstract translation: 本发明提供一种与金属基材一起使用的涂料组合物，其提供了对金属的粘合性，不会产生有害粉尘，耐腐蚀性和可再涂性的耐砂性。 本发明的涂料组合物包含聚氨酯膜形成组分和组合物中存在的有效降低涂层在基材处的腐蚀和粘合损失的量的防腐蚀组分。 施加到金属基底，预先涂覆的基底以及塑料基底上的涂层的固化膜在盐雾室暴露后具有改进的耐腐蚀性。
