Epoxy Mounting Systems
High Performance Choices
Excellent Pore Penetration and InfiltrationChoose Buehler’s epoxy media when pore penetration and sample quality are your top priorities. Easy-to-mix precise ratios make it a great choice in the lab.
Highest Quality Mounts with Fast CureAchieve the best mounting performance in your labs with Buehler’s EpoKwick® FC and EpoHeat® CLR. EpoHeat CLR cures in as little as 60 minutes with a curing oven, and EpoKwick FC cures only in 120 minutes at room temperature.
Epoxy Systems Selection Guide
Epoxy media is the preferred castable system when you need excellent infiltration in the most feasible cure time possible. Buehler offers a variety of products to meet your needs for speed, pore penetration, low curing temperature, and more.
|General-purpose mount media with an excellent balance of good hardness and low shrinkage.
|6 hrs @ room temp
|Combines very low viscocity and extremely low shrinkage with good hardness and a fast cure. EpoKwick FC is the fastest Buehler epoxy without use of an oven.
|2 hrs @ room temp
|Combines low viscosity and low cure temperature with strong adherence and good pore penetration
|9 hrs @ room temp
|When peak exotherm is not of concern, EpoHeat saves time when used in conjunction with an oven, providing strong sample infiltration for porous materials and materials with fine features
|1 hrs @ 149°F [65°C]
|Selection Guide Notes
|Values are compared to other Buehler medias and based on a one to three scale. Best values are ranked as a value of three.
|Viscocity / Infiltration
|For general applications, particularly when low viscosity isn’t required. Also ideal when using heat sensitive samples.
|Aerospace coatings and other porous samples insensitive to heat.
|For vacuum impregnation of intricate parts including heat sensitive materials such as electronic boards.
|When processing large quantities of samples, large volume mounting, vacuum impregnation or applications which require a long pot life.

Epoxy Mounting Tips and Tricks
- Some epoxies can be cured more quickly by gently heating, which accelerates exothermic reactions. Use caution using excessive heat.
- When mixing, tilt the cup containing the resin and hardener slightly and gently work the resin and hardener together using a lift and stir motion.
- To get the best results, use a vacuum system to evacuate air from samples and pour under vacuum. This best fills gaps and pores in the specimen with epoxy. Cycling the vacuum greatly improves penetration of the sample.
- Epoxies are sensitive to the ratio of resin and hardener. Be sure to follow the recommended mixing ratio for each product. Measuring by mass is recommended, especially when mixing small quantities.
- Epoxy systems are sensitive to shelf life, which depends on proper storage. Keep out of excessive high or low temps and extreme humidity. It is good practice to date your containers when received.
