3M™ Fluorinert™ Electronic Liquid FC-70 is a clear, colorless, fully-fluorinated liquid. Like other Fluorinert electronic liquids, Fluorinert liquid FC-70 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-70 ideal for many electronics applications, including vapor phase soldering and thermal management. An ideal fluid for use in condensation reflow soldering, the saturated vapor generated from boiling Fluorinert liquid FC-70 is very dense and easily contained. The elimination of oxygen allows for use of mild flux compounds, simplifying the cleaning of finished circuit boards. Other uses for Fluorinert liquid FC-70 include heat transfer, electronics testing and inert reaction media.
