    摘要: Coating compositions for coil coating, methods for making such coating compositions and coil coating methods are provided. In an exemplary embodiment, a coating composition includes an aqueous carrier and a film-forming binder dispersed in the aqueous carrier. The film-forming binder contains an epoxy-amine adduct and a blocked polyisocyanate crosslinking agent. The film-forming binder has associated amine/acid groups until subjected to heat of at least about 165.5° C. (330° F.). The coating composition also contains a pigment and a grinding resin. The coating composition has a solids content of at least about 40 wt. % based on a total weight of the coating composition.
