dicyandiamidebased

Dicyandiamidebased refers to compounds or materials that have dicyandiamide as a primary component or structural element. Dicyandiamide, also known as cyanoguanidine, is a dimer of cyanamide. It is a white crystalline solid with the chemical formula C2H4N4. This compound is formed by the dimerization of cyanamide under alkaline conditions.

In its pure form, dicyandiamide has various industrial applications. It is used as a slow-release nitrogen fertilizer due to its low water solubility, which allows for gradual decomposition and nitrogen availability to plants. It also serves as a precursor for the synthesis of other chemicals, including melamine, guanamines, and guanidine salts.

When referred to as "dicyandiamidebased," it typically implies that dicyandiamide is a key ingredient contributing to the properties of a larger system or material. For example, dicyandiamidebased resins are thermosetting polymers formed by the reaction of dicyandiamide with epoxides or other resins. These resins are known for their excellent thermal stability, mechanical strength, and adhesive properties, making them suitable for applications in coatings, adhesives, and composite materials. The presence of dicyandiamide in these formulations often acts as a curing agent or hardener. The term can also extend to other chemical formulations where dicyandiamide is a significant additive influencing the overall performance.
