3M™ Novec™ 73DE

  • Cleaning of greases, oils, silicons
  • Solvent for mono-solvent (vapor & immersion cleaning) process
  • Very low HSE impact & very low surface tension

3M™ Novec™ 73DE Engineered Fluid is designed primarily for heavy-duty vapor degreasing or immersion cleaning, featuring high solvency, low surface tension, non-flammability and fluid stability. Novec 73DE fluid is a high performing, cost-effective replacement for n-propyl bromide (nPB or 1-bromopropane), trichloroethylene (TCE), ozone-depleting hydrochlorofluorocarbons (HCFCs) like HCFC-225 (Asahiklin AK-225) and HCFC-141b and high global warming potential (GWP) hydrofluorocarbons (HFCs) for a wide range of cleaning applications. Vapor degreasing with Novec 73DE fluid can also help save you time and money over aqueous cleaning by offering faster cycle times, lower energy usage and improved cleaning of parts with complex geometries.
