Three Classic Industrial Applications of Dicyandiamide:

Construction Materials Industry: Concrete Accelerator

Dicyandiamide reacts with cement hydration to form ettringite; a typical formula uses a ratio of cement to dicyandiamide of 1:0.03%, suitable for anti-freezing in winter concrete construction.

Textile Printing and Dyeing: Anti-migration Agent

As a finishing agent, an addition of 0.1-0.3% can improve the color fastness of fabrics such as polyester, nylon, and spandex by over 30%.

Electronics Industry: Moisture Absorbent

Suitable for the storage of circuit boards and the storage method involves mixing dicyandiamide with silica gel at a ratio of 1:1, maintaining humidity ≤60% RH.
