72DE - 3M NOVEC 72DE Engineered Fluid
3M™ Novec™ 72DE Engineered Fluid is a blend of methyl nonafluorobutyl ether (C4F9OCH3), ethyl nonafluorobutyl ether (C4F9OC2H5), and trans-1,2-dichloroethylene (t-DCE). In this mixture of solvents the t-DCE forms azeotropes with each of the hydrofluoroether components. The blend has been analyzed during evaporation and extended use in a vapor degreaser and found to have a consistent composition that is safe and effective for medium- to heavy-duty degreasing applications.
Novec 72DE fluid is ideal for a wide range of cleaning applications. It is intended to replace ozone depleting and chlorinated solvents as well as other solvent systems that do not have as favorable health, safety, or environmental properties. This Novec product has zero ozone depletion potential and other favorable environmental properties (see Table 2). 3M Industrial Hygiene monitoring indicates there is a large margin of safety between the exposure guidelines that have been established for each of the components and exposures anticipated from intended end-use applications.
The high solvency and low surface tension, nonflammability and stability of Novec 72DE fluid make it ideal for immersion and vapor degreasing applications. These properties also make the solvent ideal for certain coating and lubricant deposition applications where increased solvency is desired.
