Methyl perfluoroisobutyl ether (CAS 163702-08-7) is a high-performance hydrofluoroether (HFE) fluid. It is a clear, colorless, and low-odor liquid designed to provide a safe, sustainable alternative to ozone-depleting substances and high-GWP solvents. Methyl perfluoroisobutyl ether (CAS 163702-08-7) is our specialized solution for users seeking a direct replacement for 3M Novec 7100. It features an excellent balance of boiling point, low surface tension, and high dielectric strength, making it perfect for precision cleaning of sensitive electronics and as a heat transfer medium in demanding industrial environments.

• Direct 1:1 Replacement: Specifically engineered to match the performance and physical properties of 3M Novec 7100; no process re-validation required in most applications.
• Non-Flammable & Safe: Has no flash point and is not classified as a flammable liquid, significantly increasing workplace safety.
• Environmental Excellence: Zero Ozone Depletion Potential (ODP) and a low Global Warming Potential (GWP), ensuring compliance with the latest environmental regulations.
• Low Surface Tension: Penetrates extremely small crevices and complex geometries for superior cleaning of high-density electronic assemblies.
• High Dielectric Strength: Non-conductive and safe for use in energized electrical equipment and as a direct-contact coolant.
• No Residue: Evaporates quickly and completely, leaving no spots or film on the cleaned substrate, eliminating the need for a separate drying step.

Standard industrial packaging options for Methyl perfluoroisobutyl ether include:

• 250kg high-purity HDPE-lined steel drums (Standard export packaging).
• 1200kg IBC tanks for high-volume automated cleaning systems.
• ISO Tanks for large-scale international bulk maritime transport.
• All containers are vacuum-sealed and moisture-protected to maintain the ultra-dry specifications required for electronic applications.

Methyl perfluoroisobutyl ether is a highly stable liquid. It must be stored in a cool, dry, and well-ventilated warehouse. While non-flammable, it has a moderate boiling point (61°C), so containers must be kept tightly sealed to prevent evaporation loss. Store away from strong bases and strong oxidizing agents. Properly stored in its original, unopened container, it has a shelf life of at least 24 months.
