Dicyandiamide

Alzchem AG (formerly known as SKW Trostberg), has been producing Dicyandiamide (DCD) at its technically advanced and environmentally friendly plant in Schalchen since 1950. With an annual capacity of 25,000 tons, it is one of the largest in the world and the only DCD source outside of China.

DCD is used in a wide range of applications. For example, as a synthesis building block in active pharmaceutical ingredients (API’s) such as Metformin, as a hardener in epoxy industry applications and as a nitrification inhibitor for agricultural fertilisers. Alzchem also uses DCD internally as a raw material for forward-integrated intermediates for the production of guanidine salts, guanamines and DCD-based condensation products, which are used in areas such as airbags, wastewater treatment, flame retardants, textiles and leather, and pulp and paper.

Where is Dicyandiamide used?

Applications

Starting Material for Metformin

TROPHARM is a high-purity dicyandiamide grade
Used in large quantities in the pharmaceutical industry as a starting material to produce Metformin
Metformin is used for the treatment of type 2 diabetes

Long-lasting Nitrogen Fertilizer

DCD is used in agriculture to stabilize urea
It increases the useful period of the fertilizer and prevents the environmentally harmful leaching of nitrates on fertilized fields

DYHARD^® 03

Is used as a hardener for epoxy resin applications
Printed Circuit Boards (PCB) are typically made from glass fiber which are impregnated with epoxy resin, hardeners and accelerators
Multiple layers are laminated under high pressure and cured with Dicyandiamide

DCD-Formaldehyde-Polycondensates

Used to improve wet strength of colourations and prints (Dyefixing) and to enhance crease resistance
Act as a formaldehyde acceptor in high-grade textile finishing (refining)
Also used for flame-resistant finishing in textiles, often in combination with phosphates

Flame retardant additive

Impregnation of paper or wood to achieve flame-retardant properties:
e.g. filter media for clean air in engines
DCD as a substitute for melamine in intumescent coatings: additive in fire protection

Flocculating Agents

Dicyandiamide and formaldehyde based cationic resins
Used in industrial wastewater treatment
Primarily applied in flocculation of wastewater plants, paper mills and the dyestuff industry

Made in Germany, Ecovadis Seal, TÜV
