3M  Fluorinert Electronic Liquid FC-70  11LB/ 5 KG  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 nontoxic and leaves essentially no residue upon evaporation.

Features :-

• 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.
