Technical content

3M™ Novec™ 71DE Engineered Fluid is a hydrofluoroether, Methyl Nonafluorobutyl Ether (C4F9OCH3), in an azeotrope formulation with trans-1,2-dichloroethylene (t-DCE). This mixture is a true azeotrope, with constant vapor and liquid composition at its boiling point. This fluid is ideal for medium-duty cleaning and degreasing tasks, as well as spe cialty solvent applications, and is intended to replace ozone-depleting materials in many applications. It has zero ozone depletion potential and other favorable environmental properties (see Table 2). 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, nonflammability and constant composition during boiling of Novec 71DE fluid make it ideal for immersion and vapor degreasing applications. These properties also may make the azeotrope ideal for certain coating and lubricant deposition applications where increased solvency is required.

Regulations on Chlorine-Containing Solvents Table 3 Regulation Trans-1,2- dichloroethylene Trichloroethylene Perchloroethylene Methylene Chloride VOC Designation Yes Yes Yes No Regulated if Emitted into Water Yes Yes Yes Yes Hazardous Air Pollutant No Yes Yes Yes Annual Reporting (EPCRA 313) (SARA) No Yes Yes Yes OSHA List of toxins/carcinogens No Yes Yes Yes Regulations and Reporting Because of its favorable health and environmental properties, trans-1,2-dichloroethylene (t-DCE) is less regulated in the areas noted compared to the other chlorinated solvents in Table 3. Regulations affecting 3M™ Novec™ 71DE Engineered Fluid include VOC emissions of t-DCE and ethanol and reporting requirements if trans is emitted into water or if a spill of 2000 lbs. or more of Novec 71DE fluid occurs. t-DCE is not considered a Hazardous Air Pollutant (HAP) and is not subject to annual reporting requirements.
