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.


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.

Commonly known as dicyandiamide, the white crystalline compound is the dimer for cyanamide or for cyanoguanidine.

Dicyandiamide crystals melt at 210° C, and are soluble in water and alcohol. Other uses for the compound are in the manufacture of fertilizers, explosives, oil well drilling muds, pharmaceuticals, and dyestuffs.

Dicyandiamide (DICY or DCD), also known as Cyanoguanidine, is a non-hazardous, non-volatile, white crystalline powder with the molecular formula of C2H4N4 and CAS number 461-58-5.


Dicyandiamide is a nitrogen-based molecule (66% by weight) with high reactivity that is used in a wide variety of applications across multiple industries. Applications include:

  • Flame retardant additive in timer, paper, and textile industries
  • Slow/continuous release nitrogen fertilizer
  • Hardener/curing agent in Epoxy resins
  • Powder coatings
  • Dielectric coatings
  • Adhesives
  • Water treatment chemicals
  • Dye fixing
  • Pharmaceutical applications
  • Stabilizer compound for PVC flooring
  • Floatation depressant in copper ores

Fertilizer Applications:

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 Chemical Company has been an active supplier of Dicyandiamide in the Americas for the past 30 years.
