Fluorinert FC-770 is the replacement fluid for Fluorinert FC-77, that was obsoleted in October 2007.
Fluorinert Electronic Liquid FC-770 is a clear, colorless, fully-fluorinated liquid. Like other Fluorinert electronic liquids, Fluorinert liquid FC-770 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. FC-770 liquid is chemically stable, compatible with sensitive materials, nonflammable and practically non-toxic.
MILITARY STANDARD TESTING FLUID
The high dielectric strength and wide liquid range of Fluorinert liquid FC-770 allows its use in a variety of testing applications, including electronic reliability and hermetic seal/gross leak, and thermal shock testing. Hermetic seal/gross leak testing generally follows Military Standards 883-1014, 750-1071 and 202-112; FC-72 liquid conforms to these specifications.
HEAT TRANSFER FLUID
With a pour point of -127°C and excellent low temperature viscosity, Fluorinert liquid FC-770 is an ideal fluid for use in low temperature heat transfer applications. Its high dielectric constant also means that it will not damage electronic equipment in the event of a leak or other failure.
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 non- fluorinated 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 30˚C to 215˚C and pour points as low as -127˚C.
