Dicyandiamide is non-flammable. Dicyandiamide is often used as a curing agent for epoxies and as a used as a stabilizer compound for PVC flooring. Another popular use of Dycyandiamide (DICY) is a flame retardant additive in the paper and textile industries. Dicyandiamide can be used as a slow release fertilizer.

DICYANDIAMIDE PURE is produced from the polymerization of cyanamide in the presence of a base. It is typically pure white crystals, stable when dry and soluble in liquid ammonia.
Dicyandiamide is white prismatic crystalline powder with a solubility of 2.26% in water at 13℃. It is easily soluble in hot water, and it will decompose slowly to produce ammonia when the aqueous solution is above 80℃.
