Dicyandiamide is widely used as a curing agent in epoxy resins, enhancing their mechanical and thermal properties, making them suitable for coatings, adhesives, and composite materials in industries like aerospace and electronics. It also serves as a flame retardant in polymers, improving fire resistance in plastics and textiles. In agriculture, it acts as a slow-release nitrogen fertilizer, promoting plant growth while minimizing nutrient loss. In the paper industry, it is used as an additive to improve the strength and durability of paper. Additionally, it is employed in the production of pharmaceuticals, dyes, and explosives due to its reactive chemical structure. Its versatility makes it a valuable component in various industrial and agricultural applications.
