Dicyandiamide C2H4N4 CAS: 461-58-5 - High-Quality Chemical from China Suppliers and Factory
Dicyandiamide, abbreviated as DICY or DCD, is a dimer of cyanamide and also a cyanide derivative of guanidine. It is a white crystalline powder. It is soluble in water, alcohols, ethylene glycol and dimethylformamide, and is almost insoluble in ethers and benzene. It is non-flammable. It is stable when dried.
Dicyandiamide curing agent belongs to one of the earliest types of latent curing agents that are heated for curing. It is in solid form at room temperature and insoluble in epoxy resin. It is dispersed in epoxy resin in the form of microparticles and then undergoes heating reaction. Once heated to near the melting point, it begins to dissolve and rapidly react for curing.
Dicyandiamide is a white crystalline dimer of cyanamide and a derivative of guanidine, widely used in industrial applications as a latent curing agent.
It is soluble in water, alcohols, ethylene glycol, and dimethylformamide (DMF), but almost completely insoluble in benzene and ethers.
Yes, Dicyandiamide is non-flammable and remains very stable as long as it is kept in a dry environment.
It acts as a latent curing agent. At room temperature, it remains solid and insoluble in epoxy resin. It only reacts once heated near its melting point, where it dissolves and triggers the curing process.
It is called "latent" because it can be mixed into epoxy resin without reacting at room temperature, allowing for long shelf-life of the mixture until heat is applied.
