New Two Component Nickel Conductive Epoxy Adhesive

Master Bond Inc. of Hackensack, New Jersey has developed a new two component, room temperature curing, nickel filled, electrically conductive epoxy adhesive called EP76M. EP76M has a convenient one to one mix ratio by weight or volume. It has a volume resistivity of 5-10 ohm-cm and excellent low outgassing properties. It has a thermal conductivity of 8-9 BTU/in/ft²/hr/°F. EP76M readily develops a tensile shear strength of 2,000 psi when measured and cured at room temperature.

Master Bond EP76M has superior durability, thermal shock and chemical resistance. It exhibits high bond strength to similar and dissimilar substrates. It has a coefficient of thermal expansion of 30 in/inx10⁶/°C. EP76M has a service operating temperature range of -60°F to +250°F. A higher temperature version called EP76MHT can resist up to 400°F.

EP76M is easy to apply. Contact pressure is only required for cure. The adhesive spreads evenly and smoothly. It is 100% reactive and does not contain any diluents or solvents. Cures can be accelerated by the use of heat. Parts A and B are both colored gray. EP76M is available for use in glass jars and metal containers. They are packaged in small and larger sizes (pint and quart units) for convenient application.
