Master Bond EP40TC is a two part epoxy system, designed for bonding, sealing and encapsulating applications where thermal conductivity and electrical insulation are required. With a high thermal conductivity value of 8-11 BTU•in/(ft2 •hr•°F) [1.16-1.60 W/(m•K, it is formulated with a small particle size filler making it ideal for filling small cavities and applying the product in thin sections. Its volume resistivity is greater than 1015 ohm-cm.
