Abstract: 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.
