3M-Novec HFE7100

3MTM NovecTM 7100 Engineered Fluid, methoxy-nonafluorobutane (C4F9OCH3), is a clear, colorless and low-odor fluid intended to 
replace ozone-depleting substances (ODSs) and compounds with high global warming potential (GWP) in many applications
This proprietary fluid has zero ozone depletion potential and other favorable environmental properties (see Table 2). It has one of the best toxicological profiles of CFC replacement materials, with a time-weighted average exposure guideline of 750 ppm (eight hour average). Novec 7100 fluid is compatible with most metals and hard polymers. Soft and elastomeric materials should be limited to compounds that contain the least amount of extractable plasticizer.
The high boiling point and low surface tension of Novec 7100 fluid make it ideal for use in vapor degreasing applications as a neat (pure), azeotropic component or co-solvent parts cleaner. In addition, its chemical and thermal stability, non-flammability and low toxicity make it useful for many other industrial and specialty solvent applications (see below).
