Abstract
A precursor composition, especially useful for making a patching and coating composition, and having unusual physical properties, comprises at least one non-air-blown, solvent extracted asphalt, at least one polyhydroxy polymer, at least one polyhydroxy compound, at least one polyamine, at least one solvent, and, optionally, at least one filler. This precursor composition, where combined with at least one polyisocyanate, forms a composition especially useful for coating and for patching coating.
