Compositions are disclosed which include between about 0.05 to about 5 or less wt. % of at least one acrylate monomer based on the total weight of the composition. The acrylate monomer reduces the peak cure temperature, thereby accelerating the rate of cure, without sacrificing completeness of the cure or the release performance of the cured product. The addition of the acrylate monomer also enables a reduction in the amount of costly platinum catalyst required to effectively cure a composition. In addition to the acrylate monomer, the compositions also include a silicone base polymer, a crosslinking agent, and platinum catalyst. The cured compositions exhibit properties useful for incorporation into release liners, adhesive articles, medical products and gaskets. 1. A composition comprising:a) a silicone base polymer; andb) a cure accelerator, the cure accelerator comprising an acrylate monomer present in an amount between about 0.05 to about 5 wt. % based on the total weight of the composition.2. The composition of claim 1 , wherein the silicone base polymer is a vinyl functional silicone base polymer.3. The composition of claim 1 , wherein the silicone base polymer is present from between about 50 wt. % to about 95 wt. % of the total weight of the composition.4. The composition of claim 1 , wherein the composition is uncured.5. The composition of claim 1 , further comprising an O-vinyl ether compound.6. The composition of claim 5 , wherein the O-vinyl ether compound is selected from the group consisting of 1 claim 5 ,4 cyclohexanedimethanol divinyl ether claim 5 , butanedioldivinylether claim 5 , and dodecylvinylether.7. The composition of claim 5 , wherein the O-vinyl ether compound is present from between about 0.01 wt. % to about 10 wt. % of the total weight of the composition.8. The composition of claim 1 , wherein the acrylate monomer is selected from the group consisting of a mono- claim 1 , di- claim 1 , tri- claim 1 , or multifunctional acrylate monomer.9 ...
