和水反应。环氧包埋介质在通过电子显微镜的研究中常用于生物组织。通常，由三个部分组成；Epon 812树脂，一种酸酐硬化剂和一种促进剂。 在发电机、汽车用电机、变压器、转子等绝缘领域用作环氧树脂的固化剂、 FRP/FWP 等。 Epoxy embedding medium is generally used for biological tissues during study by electron microscopy. Usually, it consists of three components; Epon 812 resin, an anhydride hardener and an accelerator. It was used during transmission electron microscopy done for the analysis of epithelial cells; during a study performed to understand the epithelial cell growth and stratification in minimal culture conditions.
