Dicyandiamide, also known as cyanoguanidine and carbamidine dicyanide, is a nitrogen-rich crystalline compound used as a latent curing agent and reactive intermediate in epoxy resin curing systems. It participates in thermally activated addition reactions with epoxy groups, providing controlled reactivity and extended storage stability in formulated resin systems while enabling crosslinking during heat processing. In industrial chemical manufacturing, dicyandiamide is typically applied within solid or powder-based formulations for resin compounding and intermediate synthesis (CAS 461-58-5). For industrial supply requirements, the material is available with competitive factory pricing, customized specifications, complete documentation including MSDS, TDS, COA, and options for bulk supply.

FAQ - Technical & Supply Chain
-
Q:
Are dicyandiamide and cyanoguanidine the same chemical substance?
A: Yes. Dicyandiamide and cyanoguanidine are alternative names for the same compound and correspond to a single CAS identity. -
Q:
Is this hardener suitable for one-component epoxy formulations?
A: Dicyandiamide is typically applied as the standard latent curing agent for single-component epoxy adhesives and powder coatings, as it remains inert at room temperature and only initiates crosslinking when heated (typically above 170°C).
