Master Bond launches Master Bond Supreme 11AOHTLP, 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 100-gram batch). This makes it suited for demanding situations where more time for fixturing is needed.
 

Reliable Electrical Insulation Properties

Master Bond 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 3,200-3,400 psi, a tensile strength of 7,000-8,000 psi, a compressive strength of 20,000-22,000 psi 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).
 

Bonds Well to Wide Variety of Substrates

Master Bond Supreme 11AOHTLP cures at room temperature in 2-3 days, and faster with heat, in 2-3 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 3-4 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.
