3M™ Fluorinert™ Electronic Liquid FC-72

3M™ Fluorinert™ Electronic Liquid FC-72 is a clear, colorless, fully-fluorinated liquid. Like other Fluorinert electronic liquids, Fluorinert liquid FC-72 is thermally and chemically stable, compatible with sensitive materials, nonflammable, practically non-toxic and leaves essentially no residue upon evaporation. This unique combination of properties makes Fluorinert liquid FC-72 ideal for many electronics applications, including quality and reliability testing. Fluorinert liquid FC-72 conforms to Military Specification 883 as a detector fluid in a vacuum/pressure vessel used in gross leak testing. Its inert nature makes Fluorinert liquid FC-72 a useful reaction medium.
