應用
CAD-2000端氨基聚醚是(shi)(shi)一(yi)種(zhong)聚氨(an)(an)酯用(yong)(yong)(yong)活性(xing)擴鏈劑。有(you)(you)著典型伯(bo)胺反(fan)應(ying)(ying)性(xing)質。因(yin)其(qi)具(ju)有(you)(you)獨(du)特(te)的化(hua)學(xue)結構,CAD-2000在環氧行業有(you)(you)廣泛地應(ying)(ying)用(yong)(yong)(yong)。在環氧應(ying)(ying)用(yong)(yong)(yong)中(zhong),很少(shao)單獨(du)的使(shi)用(yong)(yong)(yong),更多的是(shi)(shi)和(he)(he)其(qi)它(ta)固化(hua)劑一(yi)起使(shi)用(yong)(yong)(yong),特(te)別是(shi)(shi)和(he)(he)其(qi)它(ta)的端氨(an)(an)基聚醚產(chan)品如(ru)CAD-230、CAD-400、CAT-403等一(yi)起反(fan)應(ying)(ying),通(tong)過使(shi)用(yong)(yong)(yong)CAD-2000產(chan)品,可以(yi)有(you)(you)效地增強(qiang)環氧制(zhi)品彎(wan)曲拉伸性(xing)能(neng);CAD-2000一(yi)種(zhong)較好(hao)(hao)的應(ying)(ying)用(yong)(yong)(yong)是(shi)(shi)通(tong)過陰極(ji)性(xing)電鍍金屬著底色(se);CAD-2000鹽是(shi)(shi)好(hao)(hao)的稀釋液體。
安全性能和毒性
CAD-2000端氨基聚醚(mi)口(kou)服微毒;皮膚吸收無毒,但(dan)對皮膚有弱刺激性;對眼(yan)睛有強刺激性;當(dang)裝(zhuang)卸使用(yong)(yong)CAD-2000時要用(yong)(yong)防護罩(zhao)擋(dang)住臉部。若不(bu)慎接觸(chu)到(dao)眼(yan)睛必須立(li)即用(yong)(yong)水(shui)清(qing)(qing)洗(xi)至(zhi)少(shao)5分鐘(zhong),并(bing)作必要的醫療觀察。撒至(zhi)皮膚上應用(yong)(yong)肥皂和(he)水(shui)及時清(qing)(qing)洗(xi)。
包裝貯存運輸
CAD-2000通常(chang)為200Kg鐵桶充(chong)氮封裝(zhuang),避光貯存,防熱、防潮,保質期一年。
