Coating compositions for coil coating, methods for making such coating compositions and coil coating methods

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 organic solvent carrier and a film-forming binder dispersed in the organic solvent carrier. The film-forming binder contains an epoxy-amine adduct and a blocked or unblocked polyisocyanate crosslinking agent. The film-forming binder has associated amine groups until subjected to a temperature 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 50 wt. % based on a total weight of the coating composition.
