• Removal of wide range of contaminants
  • Vapor phase (mono-solvent) process
  • High cleaning power & ultra-low GWP
  • 3M Novec 73DE replacement

Developed as a drop-in replacement for trichlorethylene, NPB and other solvents with a high Health, Safety & Environmental impact. While reducing substantially the HSE impact, the degreasing power is at an equivalent level. The very low surface tension allows to penetrate very tight or difficult to access spaces, providing a deep cleaning and rinsing.

The newly developed PROMOSOLV NEO range represents our products with an Ultra-low to No GWP & low atmospheric lifetime, in order to reduce global warming impact. The solvency power has also been improved, which contributes to an even better & faster cleaning performance.

PROMOSOLV NEO B2 It is dedicated to remove most kind of oils and greases, with the exception of water-based lubricants. Furthermore it is suitable for removing waxes and particles. Depending on the nature of polymerized materials, some varnishes, adhesives, inks & paints could also be removed.

PROMOSOLV NEO B2 is a drop-in  replacement for 3M Novec 73DE which is scheduled to be phased out voluntarily by end 2025. Click on the link for more info on the announcement of 3M Novec phase out.

Process example

The best process will depend on factors such as operating conditions, equipment, desired cleaning time and the nature of contaminants. Our team is ready to advise you.

Process recommendation

  • Do not remove parts too quick out of the drying zone to prevent unwanted loss of solvent.
  • Compatibility report with different materials is available on request.
