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. ##### Accessories [![Castable Molds](https://buehler.com/uk/wp-content/uploads/sites/4/2024/02/Castable-Molds.png)](https://buehler.com/uk/products/grinding-and-polishing/accessories-and-consumables/specialty-grinding-and-polishing/) [Ring Forms & Castable Molds](https://buehler.com/products/grinding-and-polishing/grinding-and-polishing-consumables/specialty-grinding-and-polishing/) [![Cups and Additives](https://buehler.com/uk/wp-content/uploads/sites/4/2024/02/Cups-and-Additives.png)](https://buehler.com/uk/products/mounting/accessories-consumables/support-clips-additives-and-mixing-cups-for-mounting/) [Support Clips, Additives, and Mixing Cups](https://buehler.com/uk/products/mounting/accessories-consumables/support-clips-additives-and-mixing-cups-for-mounting/) [![Release Agent](https://buehler.com/uk/wp-content/uploads/sites/4/2024/02/Release-Agent.png)](https://buehler.com/uk/products/mounting/accessories-consumables/mount-and-mold-release-agents/) [Release Agents and Powders](https://buehler.com/uk/products/mounting/accessories-consumables/mount-and-mold-release-agents/) ##### Related Consumables [![Acrylic Mounting System](https://buehler.com/uk/wp-content/uploads/sites/4/2024/02/Acrylic-Mounting-System.png)](https://buehler.com/uk/products/mounting/accessories-consumables/acrylic-mounting-systems/) [Acrylic Mounting Systems](https://buehler.com/uk/products/mounting/accessories-consumables/acrylic-mounting-systems/) [![Hot Compression Mounting Compounds](https://buehler.com/uk/wp-content/uploads/sites/4/2024/02/Hot-Compression-Mounting-Image.png)](https://buehler.com/uk/products/mounting/accessories-consumables/compression-mounting-powder-and-pre-molds/) [Compression Mounting System](https://buehler.com/uk/products/mounting/accessories-consumables/compression-mounting-powder-and-pre-molds/) ##### Product Literature [![Epoxy Mounting Guide](https://buehler.com/uk/wp-content/uploads/sites/4/2023/02/Epoxy-Mounting-Guide.jpg)](https://buehler.com/assets/Brochures/English/Mounting/Epoxy_Mounting_Guide_Web.pdf) [Epoxy Mounting Guide](https://buehler.com/assets/Brochures/English/Mounting/Epoxy_Mounting_Guide_Web.pdf) [![Buehler Product Catalog](https://buehler.com/uk/wp-content/uploads/sites/4/2023/08/Buehler-Product-Catalog_default_600x782.jpg)](https://en.calameo.com/buehler/read/00639329103cfc405df2c) [Buehler Product Catalog](https://en.calameo.com/buehler/read/00639329103cfc405df2c) ###### Frequently Asked Questions When do you recommend castable mounting systems over compression mounting systems?
