Abstract
A moisture curing composition comprising (a) an oxyalkylene polymer having at least one reactive silicon group in each molecule, (b) bis(3-triethoxysilylpropyl)tetrasulfane, and (c) a condensation catalyst. The presence of the bis(3-triethoxysilylpropyl)tetrasulfane in the composition provides for improved physical properties such as tensile strength and elongation. The present compositions are suitable for use in such applications as sealing materials for construction both in the form of extrudable liquid compositions and as cured preformed configurations such as tapes.
