Abstract: Curable and cured epoxy-based coating compositions are described. The curable coating compositions are typically two-part epoxy-based formulations. The cured coating composition can be used in various applications such as those in which the curable coating composition is applied to either a clean surface or to a surface contaminated with a hydrocarbon-containing material. The cured coating composition typically bonds effectively to the substrate even in the presence of a hydrocarbon-containing material.
