Supreme 11AOHTMed has 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 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.
According to Master Bond, 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).
Supreme 11AOHTMed is said to cure at room temperature in 24-36 hours and faster with heat in one-two hours at 200°F. To optimise properties, the recommended cure schedule is overnight at room temperature, followed by a post cure at 120-150°F for two-three hours or preferably longer. It bonds well to a 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.
