Abstract
A moisture curable composition comprises: (A) a polymer containing reactive hydroxyl or hydrolysable groups bonded to silicon which groups are reactive in the presence of moisture; (B) a crosslinking agent comprising at least two groups reactive with the silicon-bonded hydroxyl or hydrolysable groups of polymer (A); (C) one or more reinforcing and/or non-reinforcing fillers; and (D) a silane having the structure (R)(Y)Si—Z-G-Z—Si(R)(Y). Rand Rare alkoxy groups containing from 1 to 6 carbons, Yand Yare alkyl groups containing from 1 to 8 carbons, Zand Zare alkylene groups having from 1 to 12 carbons, Gis a chemical group containing a heteroatom with a lone pair of electrons, and m and q are independently 1, 2 or 3. Silane (D) is present in an amount of from 15 to 30% by weight of the composition and functions as a cure catalyst.
