CURABLE COMPOSITION

摘要

A curable composition comprising (A) an organic polymer containing at least one reactive silicon functional group crosslinkable to produce an elastomer by the formation of a siloxane bond in its molecule and (B) an organic silicon compound having a molecular weight of not less than 140 and represented by the formula (1): (1) wherein R1 is a residue of an alcohol or a weak acid which has a valency of n, and n is a positive integer, The composition of the invention can give a cured product having excellent modulus and elongation as well as has excellent storage stability.
