Master Bond‘s Supreme 11AOHTMed is a two-component epoxy featuring thermal conductivity and electrical insulation. This system fully passes ISO 10993-5 testing for non-cytotoxicity and is recommended for bonding and sealing medical device applications.
Supreme 11AOHTMed has reliable electrical insulation properties with a volume resistivity exceeding 1014 ohm-cm at 75° F. It also exhibits a thermal conductivity of around 4 to 5 BTU·in/ft²·hr·° F (0.58-0.72 W/m/K).
The system provides high bond strength properties with:
- A lap-shear strength of 3,200-3,400 psi
- A tensile strength of 7,000-8,000 psi
- A compressive strength of 20,000-22,000 psi
This toughened formulation is designed to withstand thermal cycling and offers a wide service temperature range from -112° to +400°F (-80° to 204° C).
Supreme 11AOHTMed cures at room temperature in 24-36 hours, and faster with heat, in one to two hours at 200° F. To optimize properties, the recommended cure schedule is overnight at room temperature, followed by a post-cure at 120° to 150° F for two to three hours or preferably longer.
It bonds well to a wide variety of substrates including metals, ceramics, glass, rubbers, and many plastics. This epoxy system has a convenient 1:1 mix ratio by weight, with the mixed material being a thixotropic paste. To eliminate the need for manual measuring and mixing, it can be packaged in double-barrel cartridges for gun kits. It’s also available in standard jars and cans, ranging in size from 1/2-pint to gallon containers.
