Masterbond has rolled out its Master Bond Supreme 3HTND-2GT epoxy system that combines electrical insulation properties and thermal conductivity. The epoxy system can be used in a variety of applications including bonding, sealing, glob top and die attach.

The toughened epoxy system bonds well to a wide variety of substrates used in electronics, including metals, composites, ceramics and many plastics. As a one component system, Supreme 3HTND-2GT does not require mixing and features a thicker viscosity with limited flow characteristics. Unlike many epoxies it can be readily and efficiently applied to a defined area. It cures quickly in 20-30 minutes at 121.11C or in 5-10 minutes at 148C with very low shrinkage.

Masterbond's dimensionally stable system is capable of withstanding rigorous thermal cycling and shocks. Thermally stable, the service temperature range for this system is first rate at -73.33C to 204.44C. It resists chemicals rather well, including water, acids, bases and many solvents. Particularly noteworthy is its low level of ionic impurities. The epoxy is yellowish tan in colour and is available in a variety of packaging including syringes, cartridges, pints, quarts and gallon containers.
