    • A stress-release mold is described for casting thermosetting compositions especially compositions designed for consumer use. At least one wall of the mold includes a stress-releasing-element characterized by having a more flexible region or regions than the remaining wall or walls of the mold and wherein the stress-releasing-element includes a region of lower curvature at least partially surrounded by a region of higher curvature. The stress-release mold greatly reduces or eliminates surface defects caused by shrinkage of thermosetting compositions as they cools. A system is also described that includes the inventive mold containing a thermosetting composition wherein the mold also serves as all or part of the package for the composition.
    • 描述了用于浇铸热固性组合物的应力释放模具,特别是为消费者使用设计的组合物。 模具的至少一个壁包括应力释放元件,其特征在于具有比所述模具的剩余壁或壁更具柔性的区域或区域,并且其中所述应力释放元件包括至少部分地包围的较低曲率区域 通过较高曲率的区域。 应力释放模具大大降低或消除了热固性组合物在冷却时收缩引起的表面缺陷。 还描述了一种包括本发明的含有热固性组合物的模具的系统,其中模具也用作组合物的全部或部分包装。
