  7. ERL-4221 (3,4-Epoxycyclohexanemethyl 3,4-epoxycyclohexanecarboxylate)

    ERL-4221 (3,4-Epoxycyclohexanemethyl 3,4-epoxycyclohexanecarboxylate)

    开始于: NT$3,450.00

    ERL-4221 is a cycloaliphatic, diepoxy functional organic compound that is a useful building block in the production of semi-hard to hard cured epoxy resins. It is incompatible with amines, acids and strong bases and will cure to form a resinous product. ERL-4221 is often used in manufacture of plastic embedding kits for electron microscopy. 了解更多
