3M™ Novec™ Engineered Fluids for precision cleaning are versatile, non-flammable, high-performing solvents.

Novec fluids can be used in either a mono-solvent or co-solvent cleaning process – an explanation is outlined in this video.

They are used in vapour degreasing and ultrasonic cleaning systems, or in aerosols or hand-wipes, and offer excellent performance and low toxicity, along with a strong environmental profile. Benefits include:

  • 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

They present a safer, more cost-effective alternative to more harmful degreasing solvents such as trichloroethylene (Trike), perchloroethylene (PERC) and n-propyl bromide (nPB) – and balance industry requirements for performance, safety and environmental protection. Typical uses include precision engineering; de-fluxing; wax and grease removal.

When used in combination with a co-solvent hydrocarbon Novec HFE’s offer truly outstanding cleaning performance in the most challenging of cleaning applications.
