Master Bond launches Master Bond Supreme 11AOHTMed, 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 in medical device applications.
Reliable Electrical Insulation and Thermal Conductivity
Master Bond Supreme 11AOHTMed has reliable electrical insulation properties with a volume resistivity exceeding 1014 ohm-cm at 75°F. It also exhibits 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 and 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°F to +400°F (-80°C to 204°C).
Convenient Mixing and Curing Properties
Master Bond Supreme 11AOHTMed cures at room temperature in 24-36 hours, and faster with heat, in 1-2 hours at 200°F. To optimize properties, the recommended cure schedule is overnight at room temperature, followed by a post cure at 120-150°F for 2-3 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 is also available in standard jars and cans, ranging in size from ½ pint to gallon containers.
