SILYLATED POLYURETHANES FOR ADHESIVES AND SEALANTS WITH IMPROVED MECHANICAL PROPERTIES

摘要

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. Th e polymer can also have between about 5 % to less than about 50 % of the NCO groups terminated with low molecular weight terminators.
