  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).

  在有氧气存在的情况下固化弹性体时，有机过氧化物配方的实施方案可显著改善表面粘性（通常包括无粘性表面）。例如，过氧化物配方可包括一种或多种选自含硫化合物、有机亚磷酸盐化合物、HALS（受阻胺光稳定剂）化合物、脂肪族烯丙基聚氨酯化合物以及由亚硝基化合物（例如 4-羟基-TEMPO）和醌类化合物（例如单叔丁基对苯二酚）组成的混合物。

  Embodiments of organic peroxide formulations provide longer scorch time protection and require fewer additives. The peroxide formulations may include, for example, at least one organic peroxide, at least one nitroxide-containing compound (e.g., 4-hydroxy-TEMPO), and at least one quinone-containing compound (e.g., mono-tert-butylhydroquinone). Embodiments of the present invention relate to organic peroxide compositions comprising scorch retarders. Embodiments of the invention also relate to crosslinkable elastomer compositions, processes for curing the elastomers, and products made by such processes.
