這是樹(shù)脂與加速劑混合提供的一種包埋介質(zhì)，包埋塊的形成過(guò)程也即樹(shù)脂聚合的過(guò)程。通常條件下，這個(gè)過(guò)程是放熱的，但是產(chǎn)生的熱是可以用冰或者冷空氣流動(dòng)來(lái)進(jìn)行控制。冷包埋樹(shù)脂特別適用于對(duì)熱或者壓力敏感的樣品。這里介紹三種材料科學(xué)上常用的冷鑲嵌（試樣浸漬）樹(shù)脂：
1. Expoxy systems 環(huán)氧樹(shù)脂類(lèi)
Epofix環(huán)氧樹(shù)脂包埋劑（鑲嵌料）:緩慢固化的透明環(huán)氧樹(shù)脂,尤其適合于復(fù)雜敏感樣品和礦物樣品的包埋，以及需要真空鑲樣的樣品。zui高使用溫度43℃。通過(guò)添加Epoxy-dye（一種熒光染料，另名epodye）,試樣的氣孔和裂紋非常容易被識(shí)別。
2. Acrylic systems 聚丙烯酸樹(shù)脂類(lèi)（亞克力樹(shù)脂）
AcryMount亞克力樹(shù)脂：對(duì)普通樣品進(jìn)行常規(guī)的鑲嵌,尤其對(duì)于小的樣品和單個(gè)的樣品，操作起來(lái)方便快捷，室溫9-10分鐘固化，透明無(wú)色。
3. Polyester systems 聚酯類(lèi)
PolyMount：用于大批量試樣的常規(guī)鑲樣，*用于無(wú)氣孔和裂紋的簡(jiǎn)單樣品。室溫45分鐘固化，透明。
這里介紹一種PolyAcryMount：一種含有填充劑的三組分樹(shù)脂，用于更復(fù)雜試樣的鑲嵌，硬度高，幾乎無(wú)收縮，良好的平面度和邊角保護(hù)。
