(ppm/ºC) 120 Maximum Continuous Operation Temp. (ºC) 130 TCE-004 is a reworkable, aluminum nitride filled, electrically Avg. Viscosity(.5 rpm, 24ºC) insulating and thermally conductive epoxy paste adhesive which exhibits outstanding flexibility for bonding materials with highly mismatched CTE (ie., Alumina to Aluminum, Silicon to Copper). The very high thermal conductivity and flexibility make it excellent for bonding thermoelectric components to heat sinks where thermal management is critical. AVAILABILITY: TCE-004 is available in the following quantity: Model Number Quantity TCE-004 10 gram kit >1X1014 ohm-cm (150ºC/60 minutes) 337,000 cp CURE SCHEDULES: Temperature 25°C 85°C 150ºC APPLICATION PROCEDURES: SHELF LIFE*: ( 1 ) Store Part A and Part B at ambient.
