Sealants based on urethane-siloxane rubbers curable under the action of moisture

Results are presented of investigations devoted to the creation of polymer compositions using oligomeric urethane-siloxane rubbers as basic polymers (foreign analogs are STO, SPUR or STP polymers). The sealants developed based on these binding materials exhibit a wide range of rates of curing, good physicomechanical characteristics, and high adhesion to various substrates. The corresponding low-, medium-, and high-modulus polymer compositions may find wide application in automobile and transport engineering, shipbuilding, the construction industry, and other fields.
