3M Novec7100 Electronic fluorination solution Cas 163702-08-7

Introduction

3M™ Novec™ 7100 Engineered Fluid, methoxy-nonaful orobutane (C4F9OCH3), is a clear, colorless and
low-odor ful id 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 ful id candidates in Table 1.
This proprietary ful id 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 ful id 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-fal mmability and low toxicity make it useful for many other industrial and specialty
solvent applications (see below).

Applications

Material Description

1Novec 7100 fluid (C4F9OCH3) consists of two inseparable isomers with essentially identical properties. These are (CF3)2CFCF2OCH3
(CAS No. 163702-08-7) and CF3CF2CF2CF2OCH3 (CAS No. 163702-07-6).

Regulatory Status

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.

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.

Short-Term Exposure Compatibility

Exceptions: Some swelling of PTFE and Silicone Rubber. Some surface oxidation of copper during heat aging.

Safety and Handling

3M™ Novec™ 7100 Engineered Fluid is nonflammable and does not exhibit flammability characteristics under 
normal operating and storage conditions. This fluid is highly resistant to thermal breakdown and hydrolysis in 
storage and during use. Recommended handling procedures are provided in the pertinent Material Safety Data 
Sheet which is available from your local 3M representative upon request. 

Environmental Policy

3M will continue to recognize and exercise its responsibility to prevent pollution at the source wherever and 
whenever possible; develop products that will have a minimal effect on the environment; conserve natural 
resources through the use of reclamation and other appropriate methods; assure that its facilities and products 
meet and sustain the regulations of all federal, state and local environmental agencies; assist, wherever 
possible, governmental agencies and other official organizations engaged in environmental activities

Packaging and Availability

3M™ Novec™ 7100 Engineered Fluid may be ordered in the following container sizes:
• 55-gallon drum; 30-gallon drum; 5-gallon pail; 1-gallon pail
• 4-ounce samples for limited or preliminary test work are available

Recycle and Disposal Options

Used Fluid Return Program

3M offers a program for free pickup and return of used 3M specialty fluids in the U.S. A pre-negotiated 
handling agreement between users and our authorized service provider offers users broad protection against 
future liability for used 3M product. The fluid return program is covered by independent third-party financial 
and environmental audits of treatment, storage and disposal facilities. Necessary documentation is provided. A 
minimum of 30 gallons of used 3M specialty fluid is required for participation in this free program.
For additional information on the 3M Used Fluid Return Program, contact your local 3M representative or call 
3M Customer Service at 800.810.8513.
