3M™ Fluorinert™ FC-40

3M™ Fluorinert™ Electronic Fluid FC-40 is a clear, colorless, thermally stable, fully fluorinated liquid ideal for use in many single-phase heat transfer applications in the semiconductor manufacturing industry. Its liquid temperature range (-57°C to 165°C) makes it ideal for a variety of applications, including etchants, ion implanters, test devices, and others.

Other uses include heat transfer for data centers, high-performance computing, power electronics, and avionics. Fluorinert Fluid FC-40 is also used for electronics testing. Because Fluorinert Fluid FC-40 is essentially a single compound, its composition does not change or decompose over time. This minimizes fluid loss, ensuring consistent transport properties.
