High temperature, electrically conductive adhesive

The EO-98HT from EpoxySet (Lincoln, RI) is electrically conductive epoxy for electrical circuits, LED attachment, die attach and grounding applications. With a volume resistivity of approximately 10-4 ohm-cm, the EO-98HT is suited for solder replacement or circuit/wire bonding where high conductivity and reliability are required. Being a silver-filled adhesive, the EO-98HT produces a very high thermal conductivity, a glass transition temperature of 136°C (277°F) and is rated for continuous use up to 250°C (482°F), making it suitable for demanding, high-temperature needs. This one-part system has a creamy consistency with a 30-day work time at room temperature and can be stored frozen for up to a year. According to the company, it can be cured as fast as 5 minutes at 150°C (302°F).
