Latent Curing Mechanism
As one of the earliest latent curing agents, DCD is solid at room temperature and insoluble in epoxy resin. It disperses as microparticles and only reacts rapidly once heated near its melting point.

❓ Frequently Asked Questions
What are the common abbreviations for Dicyandiamide?
Dicyandiamide is commonly known as DICY or DCD in industrial applications.
What is the physical appearance of DCD?
It is a white crystalline powder that is stable under dry conditions.
Is Dicyandiamide soluble in organic solvents?
It is soluble in alcohols, ethylene glycol, and dimethylformamide, but it is almost insoluble in ethers and benzene.
Is Dicyandiamide a flammable material?
No, Dicyandiamide is classified as a non-flammable substance.
Why is DCD called a "latent" curing agent?
It is called "latent" because it remains inactive and insoluble in epoxy resin at room temperature. It only triggers the curing reaction when heated near its melting point.
How is DCD dispersed in epoxy resin?
It is dispersed within the epoxy resin in the form of microparticles rather than being dissolved initially.
