Application:

Determines cobalt, nickel, copper and palladium.Organic Synthesis.Nitrocellulose stabilizer.Hardener.Detergent.Vulcanization accelerator.Resin synthesis.

Used as a latent curing agent for epoxy resin adhesives.Formulating one-part epoxy adhesives.Only when the particle size of dicyandiamide is less than or equal to 5μm (2500 mesh), it can form a suspension in the epoxy resin without precipitation.The reference dosage is 4-12 servings, and the used life of 100g epoxy resin composition is 6-12 months.When the dosage of dicyandiamide is 17 servings, the storage period is less than 2 months.When the dosage is 8 servings, the storage period can be as long as half a year.Curing conditions170℃/lh or 180℃/20min.Heat distortion temperature 125℃.Also used as curing agent for one-component waterborne epoxy adhesives.The reference dosage is 7 servings.The compound system of dicyandiamide (5-6 parts) and hydrazide (3-4 parts),It can cure epoxy resin at 120℃/45min.

As raw material of guanidine salt and melamine

Various guanidine salts can be produced by reacting dicyandiamide with acid. The benzo-substituted melamine diamine obtained by the reaction of dicyandiamide and benzonitrile is an intermediate for coatings, laminates and molding powders.

Used as dye fixing agent.

Dicyandiamide resin produced by reaction of dicyandiamide and formaldehyde can be used as dye fixing agent.

Dicyandiamide fertilizer

Dicyandiamide compound fertilizer can control the activity of nitrifying bacteria.Regulates the rate of nitrogen fertilizer conversion in the soil,Reduce nitrogen loss and improve fertilizer use efficiency.

As the fine chemical intermediate

In medicine, it is used to produce guanidine nitrate, sulfonamides, etc..It is also used to produce thiourea, nitrocellulose stabilizer, rubber vulcanization accelerator, steel surface hardener, artificial leather filler, adhesive, etc.The pharmaceutical intermediate 5-azacytosine can be obtained by the reaction of dicyandiamide and formic acid.Nitrogen doping of carbon materials as a nitrogen source.

Package: 20 kg/50 kg/100 kg per pp woven bag;

25 kg/paper-plastic composite bag for electric grade.

Storage method

Sealed storage at 2℃~8℃,storage in a ventilated and dry place,avoiding touching with other oxides.During transportation and loading, it should be protected from moisture and handled with care.
