Room temperature curing compositions containing tetrafunctional ethoxy-ketoximo silane crosslinkers

摘要

Compositions of hydroxyl endblocked polydiorganosiloxanes and tetrafunctional ethoxy-ketoximo silane mixtures containing tetraketoximosilane, monoethoxytriketoximosilane, diethoxydiketoximosilane, and triethoxymonoketoximosilane provide one package room temperature compositions. Exposing these compositions to moisture results in a rapid cure without the use of a curing catalyst.
