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℃. It is stable when dry, does not burn, low toxicity. Dicyandiamide is often used together with formaldehyde and ammonium chloride to make color fixing agent (solid Y and solid M), which is used in the textile industry. Also it used in the manufacture of adhesives, melamine, pharmaceuticals, pesticides, dyes, coatings, synthetic detergents and guanidine raw materials. It is also used as rubber vulcanization accelerator, steel surface hardener, paper flame retardant, mildew proofing agent.

Application:
1. Raw material for producing guanidine, melamine diamine.
All kinds of guanidine can be produced by reaction of dicyandiamide with acid. The reaction of dicyandiamide and phenylnitrile is the intermediate of coating, laminate and forming powder.
2. Used as a dye fixative
Dicyandiamide resin produced by the reaction of dicyandiamide and formaldehyde can be used as dye fixing agent. It is mainly used for dyeing of direct dyes, acid dyes and sulfuric dyes.
3. As an intermediate for fine chemicals
It is used to produce thiourea, nitrocellulose stabilizer, rubber vulcanization accelerator, steel surface hardener, artificial leather filler, adhesive, etc.
4. Used as curing agent of epoxy resin
It is used as latent curing agent of epoxy resin adhesive to prepare one-component epoxy adhesive. Only when the particle size of diamine is ≤5 meters (2500 mesh) can suspension body be formed in the epoxy resin without precipitation. It is also used as a curing agent for one component waterborne epoxy adhesive.
5. To test cobalt, nickel, copper and palladium. It is also used in organic synthesis, Nitrocellulose stabilizer, Curing agent, Detergent, Vulcanization accelerator and Resin synthesis.
