Biocompatibility Approvals• EPO-TEK® MED-T7110 cured at 60°C for 4 hours has been tested and is ISO 10993-5 certified (Cytotoxicity testing by MEM Elution methodology).

Sterilization Information• Epoxy performance is most influenced by surface preparation and cleanliness, overall process and handling, and finally proper curing selection. While bulk
samples of MED-T7110 may resist sterilization technologies such as autoclave steam, gaseous technologies, gamma radiation as well as liquid disinfectants,
the glue joints may differ. All users need to determine the suitability of MED-T7110 for their given application.
• MED-T7110 is generally regarded for resisting few cycles of ETO, gamma radiation and autoclave sterilization cycles.
• Gamma Radiation/ion beam may discolor MED-T7110, thus altering its appearance.
See Technical Tip # 29: Gamma Sterilization for Medical Devices and its Effect on Epoxies for more information.
