3M™ Fluorinert™ Electronic liquids are part of a family of fully-fluorinated compounds known as perfluorocarbons, or PFCs. Fluorinert liquids are premier heat transfer fluids, and have long been used as heat transfer media for extreme cooling applications.

Originally used for direct contact cooling due to their stability, they are also used in a variety of semiconductor operations such as automated testing, etching, deposition, and photolithography.

MIL-STD 883, Test Method 1014, MIL-STD 750, Test Method 1071, and MIL-STD 202, Test Method 112 specify Fluorinert liquids for gross leak testing of microelectronic circuits and components.

3M Fluorinert electronic liquids offer:

• Excellent dielectric properties

• Wide range of boiling points

• Good materials compatibility

• Low toxicity

• Non flammability

• Zero Ozone Depletion Potential (ODP)
