0121 Epoxy

High electrical & thermal conductivity

0121 is a one-component, silver-filled, electrically conductive, precision mixed, degassed, and frozen epoxy. It has a long work life, high electrical and thermal conductivity (2.2 W/mK), and a volume resistivity of 6.0E -4 (ohm-cm). These features make it ideal for microelectronic, optoelectronic, and thermal management applications. This material has a long pot life, which maintains its dispensability for 2 days, making it suitable for automated dispensing; it can also be cured quickly at elevated temperatures. 0121 also has a high thixotropic index of 3.7. User-friendly packaging allowing for easy dispensing.
