Abstract: Moisture-hardening 1-component or 2-component composition that contains at least one prepolymer with at least one hydrolysable silane group, chosen from silane-modified polyoxyalkenes, polyolefins, poly(meth)acrylates, polyurethanes, polyamides or polysiloxanes, a Sn-based catalyst and optionally adjuvants and additives, wherein the catalyst is selected from tetramethyl-stannoxy dicarboxylates.

Abstract: An organosilicon-polyurea base polymer capable of self-crosslinking under humid condition, an elastomer prepared therefrom, preparation thereof and use of the same. By using an amino-polysiloxane, a polyisocyanate, and multiple active amino-containing silane as main materials, an organosilicon-polyurea base polymer is prepared by virtue of the copolymerization thereof. The organosilicon-polyurea base polymer has excellent high- and low-temperature resistance, and solvent resistance, and relatively better mechanical properties, and is also curable at room temperature. A crosslinked network structure of intra- and inter-molecules is formed in the base polymer through inter-crosslinking of siloxane groups at terminals and side chains of the molecular chains, thereby producing adhesives, sealants, coatings and buffer layers, in particular sealants used in automotive industry.
