CURABLE COMPOSITION

摘要

PURPOSE:A composition having a long pot life and developing rapidly curing properties at high temperature, obtained by blending an organic polymer having a reactive silicon containing group with a specific curing catalyst. CONSTITUTION:(A) 100pts.wt. organic polymer having at least one reactive silicon-containing group in the molecule is blended with (B) 0.1-10pts.wt. compound shown by formula I or II (Q is 1-20C monofunctional hydrocarbon) as a curing catalyst. An organic polymer containing an alkylene oxide polymer having a repeating unit shown by -R<1>-O-(R<1> is 1-8C bifunctional hydrocarbon group) as a main chain is used as the component A. The reactive silicon- containing group is an alkoxysilyl group. A compound shown by the formula Bu2Sn(OSiMe3)2 or a compound shown by formula III is used as the component B.
