ABSTRACT:
A method and composition are provided for preparing elastomeric polymers containing a particulate rubber filler which are useful to provide relatively thick membranes for flooring, decking, roofing or other purposes and which permit the molding of a wide variety of rubber-like goods. The composition comprises a polyol, an organic polyisocyanate, an alkaline carbon dioxide absorbent and a water carrier in amounts sufficient to form a non-foaming pourable, trowelable or sprayable composition, includes rubber particles to provide increased resiliency, economy and density, and cures internally to provide a polyurethane elastomer coating. A prepolymer may be prepared as a separate component having an extended shelf life and adapted for ultimate combination with an aqueous rubber slurry in order to facilitate simple on site mixing of the composition.
