Dicyandiamide

Dicyandiamide (DICY or DCD) is a white, crystalline powder that is the dimer of cyanamide. It is soluble in water and various alcohols but insoluble in ether and benzene. As a non-flammable and stable compound, it is widely used as a heat-curing agent for epoxy resins. It cures by dispersing in the resin as fine particles at room temperature and reacting rapidly once heated to its melting point.

Packaging:

Material: Usually  PP woven bags or kraft paper bags, sometimes with an inner polyethylene (PE) liner for enhanced moisture protection.

Specifications: Common sizes include 20kg/bag, 25kg/bag, suitable for general industrial and commercial use.

• As a raw material for guanidine salts and melamine derivatives. Various guanidine salts can be produced by the reaction of dicyandiamide with acids. Phenyl-substituted melamine, obtained from the reaction of dicyandiamide with phenyl cyanide, serves as an intermediate in the production of coatings, laminates, and molding powders.

• Used as a dye fixing agent. The dicyandiamide resin, prepared by the reaction of dicyandiamide with formaldehyde, can be used as a dye fixing agent.

• Dicyandiamide fertilizer. Dicyandiamide compound fertilizers can control the activity of nitrifying bacteria, regulate the conversion rate of nitrogen fertilizer in soil, reduce nitrogen loss, and improve fertilizer efficiency.

• As a fine chemical intermediate. In pharmaceuticals, it is used to produce guanidine nitrate, sulfonamide drugs, etc.; it is also used to produce thiourea, nitrocellulose stabilizer, rubber vulcanization accelerator, steel surface hardener, artificial leather filler, adhesive, etc. The intermediate 5-azacytidine can be obtained by the reaction of dicyandiamide with formic acid.

• Used in the determination of cobalt, nickel, copper, and palladium, organic synthesis, nitrocellulose stabilizer, hardener, detergent, vulcanization accelerator, and resin synthesis.
