Robar Ruwa - Robar Nitrile Butadiene da aka Kare ta Carboxyl (CTBN)
Kadarori da Amfani
CTBN roba ce mai ruwa-ruwa mai suna nitrile tare da ƙungiyoyin aiki na carboxyl a ƙarshen sarkar kwayoyin halitta, kuma ƙungiyar carboxyl ta ƙarshe za ta iya amsawa da resin epoxy. Ana amfani da ita galibi don ƙarfafa resin epoxy. Ana iya keɓance shi bisa ga buƙatun abokan ciniki.
