Master Bond Supreme 11AOHTLP is a two component epoxy featuring thermal conductivity and electrical insulation. This system is specifically designed for bonding larger parts since it has a relatively long working life of 60-90 minutes (at room temperature for a 100g batch). This makes it uniquely suited for demanding situations where more time for fixturing is needed.
Supreme 11AOHTLP has reliable electrical insulation properties, with a volume resistivity exceeding 1014 ohm-cm at 75°F. It also exhibits thermal conductivity of 3-5 BTU·in/(ft²·hr·°F) [0.5-0.7 W/m/K]. The system provides high bond strength properties with a lap shear strength of 3,200psi-3,400psi, a tensile strength of 7,000psi-8,000psi, a compressive strength of 20,000psi-22,000psi, and a T-peel strength of 15-20 pli. 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 11AOHTLP cures at room temperature in two to three days, and faster with heat, in two to three 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 three to four hours. 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.
