Fluorinert™ FC-40

Used in nondestructive leak and thermal shock testing for military electronics according to mil spec 883.


Product Overview

A colorless, thermally stable, fully fluorinated liquid. It's wide liquid range (-57°C to 165°C) make it ideal for a wide variety of applications. The FC-40 liquid is primarily a single compound, so its composition will not shift or fractionate over time. This results in less fluid loss and insures that transport properties do not change with time.

End Markets: Electronics; Facility Infrastructure


Ideal for a variety of single phase heat transfer applications in the semiconductor manufacturing industry such as etchers, ion implanters and testers.
