Dicyandiamde (DICY) is a strongly alkaline and water-soluble white crystalline compound with the scientific name of cyanoguanidine. The chemical is the dimer of cyanamide or cyanoguanidine, which is mainly used in the production of melamine. DICY is also used as a curing agent for epoxy resins and laminates for circuit boards, powder coatings and adhesives.

Cyanamide, the amide of normal cyanic acid, is a white crystal that melts at 45° C. It is readily soluble in water, alcohol and diethyl ether. It is prepared commercially by the carbide process from the carbonate derived from limestone or by the desulphurization of thiourea in the presence of catalyst (mercuric oxide).

Cyanamide is also prepared by the action of ammonia with cyanogene halides. Cyanamide polymerizes to dicyandiamide when heated over 150° C and to tricyantriamide as well as to melamine.


TCC’s Dicyandiamide (DICY) is an intermediate for melamine production and is the basic ingredient of amino plastics and resins. It is used in the production of a wide range of organic chemicals including slow and continuous nitrogen release fertilizers, fireproofing agents, epoxy laminates for circuit boards, powder coatings and adhesives, water treatment chemicals, dye fixing, leather and rubber chemicals, explosives and pharmaceuticals.

  • Dye fixing
  • Pharmaceutical applications
  • Stabilizer compound for PVC flooring
  • Floatation depressant in copper ores

Dicyandiamide in Fertilizers

Dicyandiamide from The Chemical Company is used in fertilizer formulations as a slow/continuous release nitrogen source. There are two major ways in which nitrogen is lost from soil – denitrification and leeching. Denitrification is loss of nitrogen to the atmosphere. Leeching is when nitrogen is washed from soil through rain or irrigation. Dicy has been shown to prevent nitrogen loss through both leeching and de-nitrification in soil. This helps reduce the negative effects of greenhouse gas emission such as nitrous oxide and nitrate leaching into waterways.

The 2010 19th World Congress of Soil Sciences released a study illustrating the positive effects of Dicyandiamide in agricultural industries and the denitrification process across various types of soils and variable concentrations such as urea and bovine urine. Dicyandiamide (DCD) reduces nitrate losses from Irish soils
