Dicyandiamide CAS 461-58-5
Dicyandiamide, wanda aka gajarta a matsayin DICY ko DACD, dimer ne na cyanamide da cyano wanda aka samu na guanidine. Farin lu'ulu'u ne. Yana da narkewa a cikin ruwa, barasa, ethylene glycol da dimethylformamide, kuma kusan ba zai iya narkewa a cikin ether da benzene. Ba shi da flammable. Yana da kwanciyar hankali lokacin bushewa. Dicyandiamide wakili ne na farkon nau'in maganin latent mai warkarwa da aka yi amfani da shi. Yana da ƙarfi a cikin ɗaki kuma ba zai iya narkewa a cikin guduro epoxy. An tarwatsa shi a cikin resin epoxy a cikin nau'i na microparticles sa'an nan kuma mai tsanani don amsawa. Da zarar ya yi zafi zuwa kusa da wurin narkewa, sai ya fara narkewa kuma ya yi sauri ya warke.
