Technicure® D-10 is a pulverized grade of dicyandiamide with an average particle size of about 10 micron. The products contains fumed silica to prevent clumping and improve flow. Typically the product is used with epoxy resin between 3-8 phr. Technicure® D-10 reacts with epoxy resin at temperatures higher than 170°C unless an accelerator is used. Suggested accelerators include Technicure® LC-80, Technicure® LC-100 and substituted urea such as Technicure® MDU-11M, Technicure® PDU250M and Technicure® TDU-200M. The type and loading level of an accelerator will provide excellent balance of low temperature reactivity and formulation shelf stability. Technicure® D-10 is available without fumed silica or with a different flow control agent.
