Abstract: Embodiments of organic peroxide formulations provide significant improvements in surface tackiness (often including tack-free surfaces) when curing elastomers in the presence of oxygen. The peroxide formulations may include, for example, one or more compounds selected from sulfur-containing compounds, organophosphite compounds, HALS (Hindered Amine Light Stabilizer) compounds, aliphatic allyl urethane compounds, and blends comprising nitroxides (e.g., 4-hydroxy-TEMPO) and quinones (e.g., mono-tert-butylhydroquinone).
