Metallographic Compression Mounting
ompression mounting is widely regarded as the preferred method for securing metallographic specimens, providing durability, ease of handling, and consistent results. OnPoint Abrasives offers a full range of high-quality compression mounting compounds designed to meet various sample preparation needs.
Phenolic Powder Resin
For a cost-effective and reliable mounting solution, PhenoMount, is an excellent choice. Available in black, red, and green, this colored phenolic resin provides strong, durable mounts suitable for general metallographic applications.

Epoxy Powder Resin
For harder materials such as heat-treated steels and titanium, EpoMount, is the ideal solution. This mineral-filled epoxy resin improves edge retention, ensuring a precise and intact specimen for analysis. Its superior hardness makes it the preferred choice for demanding applications.
Conductive Powder Resin
For scanning electron microscopy (SEM) analysis, CarbonMount, offers a specialized solution. This conductive mounting compound, made from a blend of graphite and phenolic resin, eliminates the need for sputter coating by providing the necessary conductivity for electron imaging.
