It is the raw material for the production of melamine. It is also an intermediate in medicine and dyes. In medicine, it is used to prepare guanidine nitrate, sulfonamides and so on. It can also be used to produce thiourea, guanidine, cellulose nitrate stabilizer, rubber vulcanization accelerator, steel surface hardener, dyeing and dyeing fixing agent, artificial leather filler and adhesive. Electronic grade dicyandiamide has become the main development direction in the future, which is mainly used in the production of epoxy resin copper clad plate. Its excellent insulation properties are used as curing agent in the glass cloth dipping process of copper clad plate (refer to relevant literature)
