Application
Dicyandiamide is used in the production of special resins, flame retardants, guanidine salts, etc., used as fillers in artificial leather, and used as a curing agent on adhesives. The printing and dyeing industry use dicyandiamide to manufacture fixing agents. The leather industry use it to make leather retanning agents. Water treatment industry use it to make decolorant or flocculant. It can be used in electroplating and manufacturing steel surface hardener. It can also be used as fertilizer nitrification inhibitor in agriculture. Electronic grade dicyandiamide is mainly used for epoxy resin curing agents in the manufacture of copper clad laminates for the electronic information industry, inner coating films for food and beverage metal packaging, high-grade non-toxic flame retardants, additives for food plastics, special pharmaceutical intermediates.
