詳細(xì)介紹:
丙二醇甲醚醋酸酯溶劑簡介丙二醇甲醚醋酸酯(PMA)是一種高級溶劑,其分子中既有醚鍵,又有羰基,羰基又形成了酯的結(jié)構(gòu),同時(shí)又含有烷基。在同一分子中既有非極性部分,又有極性部分,這兩部分的官能團(tuán)既相互制約排斥,又各自起到其固有的作用。因此,對非極性物質(zhì)和極性物質(zhì)都有一定的溶解能力。技術(shù)指標(biāo) 品名純度%(WT)密度(D204)沸程℃(餾出物體積≥95%)酸度%(以醋酸計(jì))(WT)水份%(WT)色度(以鉑-鈷比)CAS丙二醇甲醚醋酸酯PMA99.50.965-0.975143-149≤0.02≤0.05≤10108-65-6
使用介紹丙二醇甲醚醋酸酯是性能優(yōu)良的低毒高級工業(yè)溶劑,對極性和非極性的物質(zhì)均有很強(qiáng)的溶解能力,適用于高.檔.涂料、油墨各種聚合物的溶劑,包括氨基甲基酸酯、乙烯基、聚酯、纖維素醋酸酯、醇酸樹脂、丙烯酸樹脂、環(huán)氧樹脂及硝化纖維素等。其中,丙二醇甲醚丙酸酯是涂料、油墨中最.好.的溶劑,適用于不飽和聚酯、聚氨酯類樹脂、丙烯酸樹脂、環(huán)氧樹脂等。
