3M FLUORINERT™ FC-40

FC-40 is a non-conductive, thermally and chemically stable fluid ideal for single phase heat transfer fluid applications, especially in the electronics and semiconductor industry for testers, CVD and TFT manufacturing.

Additional Information Clear, colorless, non-conductive, non-flammable, residue free, thermally and chemically stable liquid ideal for use in many heat transfer fluid applications. Its wide liquid range (-57 to 165 deg C) and compatibility makes it well suited for a variety of electronic single and two phase heat transfer applications, including in the semiconductor market for etchers, ion implanters, testers, CVD and TFT manufacturing. Because FC-40 has a narrow boiling range, its composition will change little with time, this keeps fluid loss to a minimum and insures consistent transport properties.
