Abstract
Cure-on-demand, moisture-curable, urethane-containing prepolymers having urethanes incorporated into a sulfur-containing prepolymer backbone and compositions thereof for use in sealant applications are disclosed. The cure-on-demand moisture-curable urethane-containing prepolymers are terminated with polyalkoxysilyl groups. The compositions contain a controlled-release moisture cure catalyst. Compositions containing the prepolymers provide cured sealants exhibiting improved tensile strength.
