Dicyandiamide C2H4N4 CAS 461-58-5 | China Top Suppliers & Factory for High-Quality Dicyandiamide Raw Material
Dicyandiamide (DICY/DCD) is a dimer of cyanamide and a cyanide derivative of guanidine. Appearing as a white crystalline powder, it is highly functional in industrial applications. It is soluble in water, alcohols, ethylene glycol, and dimethylformamide, while remaining almost insoluble in ethers and benzene. It is characterized by its non-flammable nature and stability under dry conditions.
As a latent curing agent, Dicyandiamide is one of the earliest types used in heat-cured systems. At room temperature, it remains in solid form and is insoluble in epoxy resin. It disperses as microparticles and only initiates a rapid curing reaction once heated near its melting point, making it ideal for stable, one-component epoxy formulations.
Frequently Asked Questions
What is Dicyandiamide (DICY)?
Dicyandiamide, also known as DICY or DCD, is a white crystalline powder that serves as a dimer of cyanamide and a cyanide derivative of guanidine.
What are the solubility properties of DCD?
It is soluble in water, alcohols, ethylene glycol, and dimethylformamide, but it is almost completely insoluble in ethers and benzene.
Is Dicyandiamide safe to store?
Yes, it is non-flammable and remains stable as long as it is kept in a dry environment.
Why is it called a "latent" curing agent?
It is called "latent" because it remains inactive and insoluble in epoxy resin at room temperature. The curing reaction only begins once the system is heated to near the melting point of the DCD.
How is Dicyandiamide used in epoxy resins?
It is dispersed into the epoxy resin as microparticles. Upon heating, it dissolves and reacts rapidly to cure the resin, making it a key component for heat-activated adhesives and coatings.
What does DCD look like?
DCD typically appears as a fine white crystalline powder.
