3M™ Novec™ 71DE Engineered Fluid

3M™ Novec™ 71DE is an azeotrope containing 3M™ Novec™ 7100 and 1,2 trans-dichloroethylene. It maintains a constant liquid and vapour composition at its boiling point. It can be used in many medium-duty cleaning and degreasing applications.

Novec 71DE fluid has a time-weighted average exposure guideline of 750 ppm (eight hour average) for the 3M™ Novec™ 7100 Engineered Fluid component, and 200 ppm (eight hour average) for trans-1,2-dichloroethylene (t-DCE). These exposure guidelines suggest there is a large margin of safety for use of Novec 71DE fluid in its intended cleaning applications. 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. For more details download the technical datasheet.
