IPC: C08L63/00
Abstract: Alkoxylated hydrophobes that include a poly(alkylene oxide) chain of at least 5 oxyalkylene units having a terminal secondary hydroxyl group or a terminal C1−8 hydrocarbyl group are effective internal mold release agents for epoxy resin moldings. The alkoxylated hydrophobe, when mixed with an epoxy resin, forms a mixture that is highly stable when heated to 80 to 100° C. and held at that temperature for a period of as much as 22 days.
