Abstract:

Base coats, methods of using base coats, and methods of producing base coats are provided. In an exemplary embodiment, a method of producing a base coat includes forming a CPO intermediate and a color intermediate. The CPO intermediate includes a chlorinated polyolefin at from about 5 to about 20 weight percent, based on a total weight of the CPO intermediate, as well as a CPO solvent. The color intermediate includes a color imparting additive and a color solvent that is different than the CPO solvent. The CPO intermediate and the color intermediate are combined to form the base coat, where the base coat includes from about 1 to about 3 weight percent chlorinated polyolefin and from about 5 to about 30 weight percent solids, based on a total weight of the base coat.

Abstract:

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.
