Dicyandiamide For Epoxy Laminates
Dicyandiamide, also known as cyanoguanidine, has long been used as a latent curing agent in powder coatings, adhesives and other fields. Dicyandiamide can be stored at room temperature for up to 6 months after mixing with epoxy resin. The curing mechanism of dicyandiamide is complex. Besides the four hydrogens on dicyandiamide, the cyanogroup also has some reactivity. When DCD is used as curing agent of epoxy resin, the curing temperature is very high, generally between 150 ℃ and 170℃. At this temperature, many devices and materials cannot be used because they cannot bear such temperature, or the curing temperature of one-component epoxy resin must be reduced due to the requirements of the production process.
