Dicyandiamide used in many
industry applications

Dicyandiamide is a chemical compound with various industrial applications. Here's a list of some of its uses:

1. Adhesives and Sealants: Dicyandiamide is used as a curing agent in the production of epoxy resins, which are widely used in adhesives, sealants, coatings, and composite materials. It helps to crosslink the polymer chains, resulting in enhanced strength, durability, and chemical resistance.
2. Water Treatment: It is used in water treatment formulations as a slow-release nitrogen fertilizer for agricultural and horticultural applications. Dicyandiamide acts as a nitrification inhibitor, reducing the conversion of ammonium nitrogen to nitrate nitrogen in soil, thus improving nutrient efficiency and reducing nitrogen losses.
3. Textile Processing: Dicyandiamide is used in textile processing as a crosslinking agent for polyamide fibers, such as nylon. It improves the mechanical properties, dimensional stability, and dyeability of nylon fabrics, making them suitable for a wide range of apparel, upholstery, and industrial applications.
4. Flame Retardants: It is used as a flame retardant additive in various polymer formulations, including plastics, rubber, and textiles. Dicyandiamide-based flame retardants act by releasing ammonia gas when exposed to high temperatures, which dilutes the flammable gases and inhibits combustion.
5. Pharmaceutical Intermediates: Dicyandiamide is used as a building block in the synthesis of pharmaceutical intermediates and active ingredients. It serves as a precursor for the production of guanidine derivatives, which are used in the pharmaceutical industry for the treatment of hypertension, diabetes, and other medical conditions.
6. Explosives: It is used in the production of explosives and propellants, such as guanidine nitrate and cyanamide. Dicyandiamide-based explosives exhibit high stability, low sensitivity, and controlled detonation characteristics, making them suitable for military, mining, and demolition applications.
7. Paper Chemicals: Dicyandiamide is used in the paper industry as a paper strength additive and retention aid. It improves the bonding strength between cellulose fibers, enhances paper strength and tear resistance, and reduces paper shrinkage and dusting during papermaking processes.
8. Animal Nutrition: It is used as a feed additive in animal nutrition to improve nitrogen utilization and feed efficiency. Dicyandiamide is added to livestock feed, poultry feed, and aquafeed to supplement dietary protein, promote growth, and reduce nitrogen excretion in animal waste.
9. Electroplating: Dicyandiamide is used in the electroplating industry as a brightening agent and complexing agent for metal deposition processes. It helps to improve the appearance, adhesion, and corrosion resistance of metal coatings on substrates such as steel, aluminum, and copper.
10. Photography: It is used in photography as a sensitizer for silver halide emulsions, particularly in the production of diazo and azo dyes. Dicyandiamide enhances the sensitivity and resolution of photographic films and papers, allowing for sharper and more detailed image reproduction.
