Abstract: An alkoxysilyl-containing polyurethane polymer composition is prepared using a urethane-forming organometallic catalyst which is then stabilized to moisture exposure by the addition of a mercapto-containing compound. The stabilized moisture-curable alkoxsilyl-containing polyurethane polymer composition is activated to moisture curing by the addition of a hydrolysis and condensation catalysts. The stabilized moisture-curable alkoxsilyl-containing polyurethane polymer composition is useful as a component in the preparation of coatings, adhesives, sealants, consumer goods and industrial goods.
