In many challenging bonding applications, elevated temperature cures are not possible. In order to overcome this deficiency, Master Bond's EP21TCHT-1 has high thermal conductivity and superior electrical insulation properties. It has a service operating temperature range of 4K to 400°F. It also has a remarkably low thermal expansion coefficient. EP21TCHT-1 is NASA qualified for low outgassing applications. It is highly recommended for use in vacuum environments. Master Bond EP21TCHT-1 is durable and possesses high physical strength properties. Adhesion to metals, ceramics, woods, vulcanized rubbers, and most plastics is excellent. Bonds are resistant to water, fuels, and most organic solvents. EP21TCHT-1 has a mix ratio of 100 to 60 by weight. It has a light paste viscosity and is easy to apply.
