Product Properties


Product Information

This fluid is ideal for medium-duty cleaning and degreasing tasks, as well as speciality solvent applications, and is intended to replace ozone-depleting materials in many applications. It has zero ozone depletion potential and other favourable environmental properties.

The increased solvency and low surface tension, non flammability and constant composition during boiling of Novec 71DE fluid make it ideal for immersion and vapour degreasing applications. These properties also may make the azeotrope ideal for certain coating and lubricant deposition applications where increased solvency is required.


  • Cleaning, rinsing and drying agent
  • Cleaning of oils, greases, waxes
  • Specialty solvent applications, including coatings
