• Phenolics – Generally, phenolics are utilized because of their comparatively low cost. Phenolics are likewise available in various colors.
• Acrylics – The primary use of compression mounting acrylics is due to its excellent clarity. It is particularly important in locating specific features in the specimen mount.
• Epoxies/Diallyl Phthalates – Glass-filled epoxy and diallyl phthalate are types of compression mounting resins utilized for providing a tougher mounting support edge around the specimen. The resins are typically used as support for the coatings’ edges, heat treated samples, as well as other specimens that require better flatness.

There’s no apparent gap between the mounting material and the specimen. The glass-filled epoxies offer excellent support to the edge of the specimen even in extremely hard samples.

• Specialized Compression Mounting Resins – The addition of fillers like copper or graphite enables the compression mounting compounds to be more conductive.

A conductive mount is used for scanning electron microscopes (SEM) to keep the specimen from accumulating a charge. A conductive mount is also used for samples that require electrolytic etching or polishing.
