Dicyandiamide
Applications
Used in the production of melamine, guanidine, pharmaceuticals, and epoxy resin curing agents. In fertilizers, it serves as a nitrification inhibitor, reducing nitrogen losses in soil. Also used in flame retardants, dyestuffs, and water treatment formulations.
Safety & Risks
Low toxicity but may cause mild irritation upon dust exposure. Avoid contact with oxidizers and moisture to maintain purity.
Packaging
Supplied in 25 kg PE-lined paper bags or drums. Store cool, dry, and tightly sealed away from heat and acids.
