3M? Fluorinert? Liquids are a family of clear, colorless, odorless perfluorinated

fluids having a viscosity similar to water. These non-flammable liquids have set the

standard in the electronics industry for over 40 years, meeting the demanding and

diverse requirements of many heat transfer, manufacturing and testing applications.

Fluorinert liquids are thermally and chemically stable, compatible with most

sensitive materials, including metals, plastics and elastomers, and are practically

non-toxic through normal routes of industrial exposure.

Fluorinert liquids are completely fluorinated, containing no chlorine or hydrogen

atoms. The strength of the carbon-fluorine bond contributes to their extreme

stability and inertness. This chemical structure also results in very low

intermolecular forces, low surface tension and essentially no solvent action on nonfluorinated

compounds.

The dielectric strength of perfluorinated liquids is high—in excess of 35,000 volts

across a 0.1 inch gap. Water solubility is on the order of a few parts per million.

The nominal boiling point of each fluid in this series is determined during their

manufacture. Fluorinert liquids are available with boiling points ranging from

30oC to 215oC and pour points as low as -101oC.
