Abstract
This invention provides a polymeric vehicle and formulated coating composition which are high in solids and use water to effect viscosities to permit application of such polymeric vehicles and formulated coating compositions with existing commercial application equipment. The polymeric vehicles and formulated coatings include at least one oligoester diol, a carbamate hardener, and in some instances, an additional crosslinking agent. The combination of oligoester diol with carbamate hardener provides a low viscosity coating composition with low to zero VOC content, and provides a coating binder with extremely good film properties.
