Performance Benefits
-
High nitrogen content – Improves nitrogen utilization efficiency in fertilizer applications and reduces nitrogen loss.
-
Effective nitrification inhibition – Suppresses conversion of ammonium nitrogen to nitrate nitrogen in soil, extending nitrogen release and minimizing leaching and volatilization.
-
Excellent curing performance – As an epoxy curing agent, it delivers products with high heat resistance, electrical insulation, and mechanical strength, suitable for electronic and coating industries.
-
Versatile chemical intermediate – Essential raw material for melamine, guanidine salts, cyanuric acid, aminoplasts, resins, pharmaceuticals, and pesticide intermediates.
-
Low toxicity and safe handling – Low toxic, with an allowable airborne concentration up to 5 mg/m³, making it suitable for industrial usage.
What is Dicyandiamide Used for
1. Agriculture & Fertilizer
- Used as a nitrification inhibitor in urea, ammonium sulfate, and other nitrogen fertilizers to reduce nitrogen loss via leaching and volatilization.
- Functions as a slow-release nitrogen source, extending the effective release period of nitrogen in soil, suitable for single application as base fertilizer.
- Ideal for cereals, fruit trees, vegetables, and other crops, especially in high-temperature, high-humidity, and well-aerated soil conditions.
2. Epoxy Resin & Coatings
- Acts as a thermal curing agent for epoxy resins, powder coatings, adhesives, and PCB laminate materials.
- Cured products exhibit excellent heat resistance, electrical insulation, and mechanical strength, widely used in electronics and anti-corrosion coatings.
3. Chemical Intermediate
- Key intermediate for melamine, guanidine salts, cyanuric acid, and other nitrogen-containing compounds.
- Used in the production of aminoplasts, resin systems, pharmaceutical intermediates, and pesticide intermediates.
4. Water Treatment & Corrosion Control
- Used in water treatment to inhibit bacterial and algal growth.
- Helps prevent pipe scaling and corrosion; employed as an auxiliary in some water treatment chemical formulations.
