WebTechnicure® Nano-Dicy Description: Technicure® Nano-Dicy is a pulverized grade of dicyandiamide with an average particle size of about 1-2 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 extremely fine particle WebJun 22, 1998 · The curing agent dicyandiamide (DICY, >98% pure) and the accelerator 2-methylimidazole (2-MI, >98% pure) were obtained from Neuto Products and Tokyo Kasei Kogyo, respectively. ... Yet this effect should be minor because of the limited solubility of DICY in acetone and the relatively large amounts of DICY used.
WebDICY’s solubility in the resin using a surfactant.8 The addition of 1.2 and 6 wt % surfactant decreased the cure kinetic activation energies relative to pure epoxy/DICY, but resulted in lower overall cure rates. It was theorized that DICY’s solubility was increased in epoxy resin by the surfactant addition, but that a film WebDicyandiamide is used in the synthesis of barbiturates. It is used as a stabilizer of ammonium dinitramide melt. It is used as hardener. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio.
