3M™ Novec™ 72DE Engineered Fluid is intended for heavy duty cleaning and degreasing applications. The high solvency and low toxicity make it an ideal replacement for ozone-depleting compounds, chlorinated solvents, and n-propyl bromide in many applications.
Novec 72DE 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 72DE fluid in its intended sonic cleaning applications. The increased solvency and low surface tension, non-flammability and constant composition during boiling of Novec 72DE 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.
