Abstract

The silylated polyurethane polymer includes a polyurethane prepolymer having between greater than about 50 to about 95% of NCO groups terminated with silane capping agents. The polymer has an improved mechanical properties. The polymer can also have between about 5% to less than about 50% of the NCO groups terminated with low molecular weight terminators.
