Patent ID: 8119724

Claim:
An uncured gasket composition curable at room temperature on a first sealing surface and positionable against a second sealing surface comprising a mixture of: a) a moisture curable silyl functionalized polyacrylate having the structure, wherein each R 1 is independently selected from a C 1 to C 6 alkyl, each R 2 is independently selected from a C 1 to C 10 alkyl, a is integer from 0-3, q is an integer from 2 to about 1,000, and A is a hydrocarbon diradical containing at least one (meth)acrylate linkage; b) at least one component which reduces shrinkage of the cured composition upon exposure of the cured composition to a hydrocarbon fluid, wherein the component is present in an amount sufficient to reduce shrinkage of the cured composition when exposed to a hydrocarbon fluid as compared to the same cured composition without the at least one component; c) optionally a filler; and d) optionally a moisture-cure catalyst.
