JEFFAMINE® D 230

JEFFAMINE® D-230 amine is a polyether diamine with low color, low viscosity, and moderate reactivity in epoxy curing. The polyether backbone gives cured resins with relatively high elongation and good toughness and thermal shock resistance. It can be blended with higher-viscosity curing agents to reduce viscosity, or with cycloaliphatics to improve the elongation of higher-Tg cured resins.The D-230 (32 phr) should be mixed thoroughly with the resin. Curing at elevated temperature is desirable to develop the full properties shown above. Good properties can be obtained, however, with cures at lower temperatures. For room temperature cures a cure accelerator (such as Huntsman Accelerator 399, 2-10 phr) is generally added.
