Novec(tm) Engineered Fluids
3M™ Novec™ HFEs strike a balance between demands for improved cleaning performance at lower cost and lower environmental impact in a safer healthier workplace.
Novec HFEs are suitable for use in vapour and immersion degreasing processes in applications including precision engineering; de-fluxing; wax and grease removal.
When used in combination with a co-solvent hydrocarbon 3M Novec HFE's offer truly outstanding cleaning performance in the most challenging of cleaning applications.Novec fluids offer:
- Low toxicity
- Zero Ozone Depletion Potential (ODP)
- Low Global Warming Potential (GWP)
- Thermal and Chemical stability
- Hydrolytic stability
- Non-corrosive
- Excellent dielectric properties
- Low viscosity and surface tension
- Wide range of boiling points
- Good materials compatibility
- Non-flammable
Application:
- Light duty cleaning
- Particulate removal, wipe cleaning
- Flux residue removal; oil and grease removal
- Light wax removal
- Co-solvent cleaning for heavy waxes, oils and greases (see also co-solvent materials such as Avantec Performance Chemicals)
- Medium duty cleaning
- Heavy duty cleaning
