Technicure® D-44

Technicure® D-44 is a pulverized grade of dicyandiamide with an average particle size of about 20 micron. The products contains fumed silica to prevent clumping and improve flow. Typically the product is used with epoxy resin between 3-8 phr. Due to larger particle size, the products offers lower exothermic heat than the finer grade of Dicy. Technicure® D-44 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 ureas such as Technicure® MDU-11M, Technicure® PDU-250M and Technicure® TDU-200M. The type and loading level of an accelerator will provide excellent balance of low temperature reactivity and formulation shelf stability.
