Application:
As raw material of guanidine salt and melamine
Various guanidine salts can be produced by reacting dicyandiamide with acid. The benzo-substituted melamine diamine obtained by the reaction of dicyandiamide and benzonitrile is an intermediate for coatings, laminates and molding powders.
Used as dye fixing agent.
Dicyandiamide resin produced by reaction of dicyandiamide and formaldehyde can be used as dye fixing agent.
Dicyandiamide fertilizer
