这是树脂与加速剂混合提供的一种包埋介质，包埋块的形成过程也即树脂聚合的过程。通常条件下，这个过程是放热的，但是产生的热是可以用冰或者冷空气流动来进行控制。冷包埋树脂特别适用于对热或者压力敏感的样品。这里介绍三种材料科学上常用的冷镶嵌（试样浸渍）树脂：
1. Expoxy systems 环氧树脂类
Epofix环氧树脂包埋剂（镶嵌料）:缓慢固化的透明环氧树脂,尤其适合于复杂敏感样品和矿物样品的包埋，以及需要真空镶样的样品。zui高使用温度43℃。通过添加Epoxy-dye（一种荧光染料，另名epodye）,试样的气孔和裂纹非常容易被识别。
2. Acrylic systems 聚丙烯酸树脂类（亚克力树脂）
AcryMount亚克力树脂：对普通样品进行常规的镶嵌,尤其对于小的样品和单个的样品，操作起来方便快捷，室温9-10分钟固化，透明无色。
3. Polyester systems 聚酯类
PolyMount：用于大批量试样的常规镶样，*用于无气孔和裂纹的简单样品。室温45分钟固化，透明。
这里介绍一种PolyAcryMount：一种含有填充剂的三组分树脂，用于更复杂试样的镶嵌，硬度高，几乎无收缩，良好的平面度和边角保护。
