The instant invention is an improved cure system composition and a method for curing chlorinated elastomer compositions. The cure system composition includes a polymercapto crosslinking agent, an inorganic base, and a quaternary ammonium salt. The quaternary ammonium salt has a formula selected from the group consisting of
wherein R
1
is an alkyl or aryl group containing between 4 and 12 carbon atoms; wherein R
2
and R
3
are independently alkyl or aryl groups containing between 1 and 8 carbon atoms; wherein the total number of carbon atoms on R
2
and R
3
are between 3 and 9; wherein R
4
and R
5
are methyl groups, and R
6
is an alkyl group containing between 2 and 8 carbon atoms; and wherein X is an anion. The method for curing a chlorinated elastomer composition according to instant invention includes the following steps: (1) providing a chlorinated elastomer composition; (2) providing a cure system composition as described above; (3) contacting said chlorinated elastomer composition with said cure system composition; and (4) thereby curing said chlorinated elastomer composition.
