Is DICY the same as DCD?

Yes — the epoxy hardener “DICY” is dicyandiamide. Only grade and particle size differ between an epoxy DICY and an agricultural DCD.

How is DCD different from a slow-release fertilizer?

DCD chemically inhibits the conversion of ammonium to nitrate in soil. It is not a coated controlled-release product — it works by slowing a microbial reaction.

How should DCD be stored?

As a stable solid: cool, dry, and away from heat and strong acids/oxidisers.

It is REACH-registered with low acute toxicity; EFSA has set a tolerable daily intake of 1 mg/kg body weight/day.

Dicyandiamide (DCD) is a versatile white crystalline intermediate best known as a urea nitrification inhibitor and as the latent epoxy hardener “DICY.” Ehlinar sources agricultural, epoxy-curing, electronic and pharma grades against your assay and particle-size specification.

Applications

AgricultureNitrification inhibitor — holds nitrogen as ammonium, cutting nitrate leaching and N₂O loss

Epoxy & compositesLatent one-component curing agent (DICY) that cures above ~150 °C

Chemical intermediatesFeedstock for guanidine, guanamine and melamine derivatives

Flame retardantsIntumescent flame-retardant systems and gas generants

PharmaIntermediate for metformin and other guanidine derivatives

Water treatmentDCD–formaldehyde resins; also adhesives, drilling fluids and dyestuffs

Grades & packaging

Agricultural/fertilizer, epoxy-curing (standard and micronised DICY), electronic/PCB and pharma grades, differing mainly in assay and particle size.

25 / 50 kg PE-lined bags
500–1000 kg supersacks

Also known as

Cyanoguanidine · 2-Cyanoguanidine · DCD · DCDA · DICY (epoxy trade)
