Patent ID: 8088851

Claim:
An uncured gasket composition curable at room temperature on a first sealing surface, comprising: (a) a (meth)acrylate component comprising a silyl-functionalized poly(acrylate) 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 of a phenylene diamine within structure I or a diphenyl amine within structure II, wherein structure I comprises: wherein R and R 1 are each members individually selected from the group consisting of C 1-12 alkyl, C 2-12 alkenyl, C 3-12 cyclo or bicycloalkyl, C 6-18 aryl, and derivatives thereof, and x and y are each individually 0-2; structure II comprises: wherein R 2 and R 3 are each members individually selected from the group consisting of C 1-12 alkyl, C 2-12 alkenyl, C 3-12 cyclo or bicycloalkyl, C 6-18 aryl, and derivatives thereof, and n and m are each individually 0-5; and combinations thereof; and (c) 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.
