FAQ - Technical & Supply Chain
-
Q:
Are Dicyandiamide, Cyanoguanidine and DCDA the same substance?
A: Yes. Dicyandiamide, Cyanoguanidine and the abbreviation DCDA are commonly used for CAS 461-58-5, formula C₂H₄N₄. The abbreviation alone should not replace the full identity on contracts, labels and COA documents, especially where modified, micronized or formulated dicyandiamide products are also offered. -
Q:
Which specifications distinguish industrial Dicyandiamide grades?
A: Agree assay, moisture or loss on drying, ash, calcium, iron, melamine and other process-related impurities where relevant, together with pH, melting behavior and the required test methods. Electronic, resin, fertilizer and other industrial uses may need different impurity limits, so approve the batch COA against the intended process. -
Q:
When should Dicyandiamide particle size be specified?
A: Specify particle-size distribution when dissolution rate, dispersion, dusting, filtration or resin cure consistency matters. Confirm whether the offer is standard crystal, fine powder, micronized material or a formulation, and agree the sieve or laser-diffraction method. Packaging should protect the powder from moisture and contamination throughout storage and container transport.
