High Temperature Resistant, Thermally Conductive Adhesive Passes NASA Outgassing Tests

Master Bond Inc., Hackensack, N.J. has developed a new two component, thermally conductive, electrically insulative epoxy adhesive called EP21TCHT-1. This compound passes NASA low outgassing specifications and has a service operating temperature range of 4°K up to 400°F. It is formulated to cure at room temperatuire or more rapidly at elevated temperatuires. EP21TCHT-1 has a mix ratio of 100 to 60 by weight and has a mixed viscosity of light paste. It is 100% reactive and does not contain any solvents or diluents.

Master Bond EP21TCHT-1 is durable and has high physical strength properties. It has excellent adhesion to metals, ceramics, glass, wood, vulcanized rubbers, and most plastics. EP21TCHT-1 also exhibits resistance to thermal cycling and can withstand exposure to water, fuels and most organic solvents. As a NASA qualified system, it is ideal for high vacuum type applications, particularly those where elevated temperature cures are not possible.

EP21TCHT-1 exhibits a tensile shear strengh, aluminum to aluminum of 2,200 psi. It has a Shore D hardness of >80 and a coefficient of thermal expansion of 18-20 in/in x 10-6°C. Additionally, its dielectric strength is 420 volts/mil and its thermal conductivity is 10 BTU/in/ft²/hr/°F.

Master Bond EP21TCHT-1 is available for use in 1/2 pint, pint, quart, gallon, and 5 gallon container kits.
