Patent ID: 8066288

Claim:
A component defining an internal chamber, comprising: a first predetermined internal combustion engine sealing surface in fluid communication with the chamber; a second predetermined internal combustion engine sealing surface aligned with the first sealing surface and in fluid communication with the chamber; and a cured reaction product of a curable composition disposed between the first and second predetermined sealing surfaces and sealing the chamber, the composition comprising: an alkenyl functional polyisobutylene oligomer; an optional functional alkenyl monomer; a silane cross-linking component having at least two silicon hydride functional groups and having structure 1: where R 1 , R 2 , R 3 , R′ 1 , R′ 2 , R′ 3 , R 4 , R 5 and R 6 are each independently selected from a methyl group; a hydrogen group; a phenyl group; a substituted hydrocarbon containing one to twenty carbon atoms or an unsubstituted hydrocarbon containing one to twenty carbon atoms; X is an integer from 1 to 1,000; y is an integer from 1 to 1000; and a hydrosilylation catalyst.
