TRA-DUCT 2902 is a smooth silver filled paste, which can be applied and cured at room temperature to give electrical and thermal conductivity. It passed cytotoxicity testing using the MEM elution method and has been used in the medical device industry in the assembly of ultrasonic transducers. Curing can be at higher temperatures to decrease processing times, and bonds metals, ceramics, glass, and several plastics. As well as being biocompatible, it complies with NASA outgassing requirements.
