Description

Dicyandiamide is a versatile and industrially significant organic compound, primarily known as a key intermediate and curing agent. Its value lies in its ability to form stable, high-performance polymers and resins, making it essential for creating durable materials. This product is critically needed by manufacturers in the epoxy resin, pharmaceutical, and specialty chemical industries for applications ranging from laminates and coatings to flame retardants and slow-release fertilizers.

Application

• Epoxy Resin Curing Agent: A primary hardener for powder coatings, electrical laminates, and adhesives, providing excellent thermal and chemical resistance.
• Flame Retardant Synergist: Used in combination with other compounds (e.g., ammonium polyphosphate) in plastics, textiles, and wood to enhance fire safety.
• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of various drugs, including guanidine derivatives and biguanides like metformin.
• Slow-Release Fertilizer Component: Acts as a nitrification inhibitor and a source of controlled-release nitrogen in agricultural formulations.
• Dye Fixative & Textile Auxiliary: Improves the wash-fastness of direct and reactive dyes on cotton and other cellulose fibers.
• Water Treatment Chemical: Used in the production of cationic flocculants and as a stabilizer in some industrial water systems.
• Synthesis of Guanidine Salts & Melamine: A fundamental precursor in the manufacture of guanidine nitrate, carbonate, and melamine resins.
• Paper & Pulp Industry: Employed as a wet-strength additive and in certain paper coating formulations.

Quality Control

Our Dicyandiamide is produced under a stringent quality management system to ensure batch-to-batch consistency and high purity. We offer grades suitable for industrial, pharmaceutical intermediate, and epoxy applications, with testing aligned to relevant customer and industry specifications. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profile, and physical parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). The product is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent caking or degradation due to moisture absorption. Keep away from strong acids and strong oxidizing agents.
