Technical content

3M™ Novec™ 7100 Engineered Fluid, methoxy-nonafluorobutane (C4F9OCH3), is a clear, color less and low-odor fluid intended to replace ozone-depleting substances (ODSs) and compounds with high global warming potential (GWP) in many applications. Its physical properties are compared with several other ODS replacement fluid candidates in Table 1. 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). 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).

3M™ Novec™ 7100 Engineered Fluid has been accepted for commercial use by regulatory agencies in the United States, Europe, Canada, Australia, Japan, Korea and the Philippines. The components of Novec 7100 fluid have been nominated to China’s draft chemical inventory. Novec 7100 fluid has been approved under the Significant New Alternatives Policy (SNAP) of the U.S. EPA. In addition, Novec 7100 fluid has been excluded by the U.S. EPA from the definition of a VOC on the basis that this compound has negligible contribution to tropospheric ozone formation. The components of Novec 7100 fluid are not on any regulated lists. Contact your local 3M representative regarding the regulatory status of Novec 7100 fluid in other countries. Toxicity Profile The toxicological testing completed on Novec 7100 fluid shows the overall toxicity is low. The material is practically non-irritating to the eyes, minimally irritating to the skin and is not a mutagen or cardiac sensitizer. It is rated “practically non-toxic” through inhalation. A 90-day inhalation study has helped establish a recommended exposure guideline of 750 ppm for an eight-hour average worker exposure per day. This exposure guideline was established by the American Industrial Hygiene Association.

Vapor Pressure and Density The variation of vapor pressure and density with temperature for 3M™ Novec™ 7100 Engineered Fluid can be calculated using the following formulas: Vapor Pressure: ln P = 22.415 - 3641.9 [1/(t+273)] Density: D = 1.5383 - 0.002269t P =Vapor Pressure in Pascals t =Temperature in °C D =Density in g/ml Materials Compatibility Continuous Exposure 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. 3M technical service engineers can suggest appropriate compounds and assist with material compatibility tests. Non-Continuous Exposure Short-term testing of Novec 7100 fluid demonstrates compatibility, after one hour exposure at boiling temperature, with a wide range of metals, plastics and elastomers, similar to the performance of perfluorinated liquids. Good short-term compatibility with particularly sensitive plastics such as polycarbonate and PMMA indicates utility in cleaning of assemblies containing many composite materials. As with most fluorinated liquids, Novec 7100 fluid will absorb into fluorinated plastics and elastomers over longer exposures.
