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.

Applications

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