    3M™ Fluorinert™ Liquid FC-770 is a non-conductive, thermally and chemically stable fluid with a wide liquid range (-125 to 95 deg C) for use in many low temperature heat transfer application such as reliability testing and cooling of electronics.

    Additional Information Clear, colorless, non-conductive, non-flammable, residue free, thermally and chemically stable liquid ideal for use in many heat transfer fluid applications. Its very wide liquid range (-125 to 95 deg C) and compatibility make it well suited for a variety of electronic single and two phase heat transfer applications, including in the reliability testing, power conversion, electronic cooling and others. Because FC-770 has an extremely narrow boiling range, its composition will not deviate with time, insuring consistent transport properties.
