3M™ Novec™ 72DA Engineered Fluid is a blend of hydrofluoroether methyl nonafluorobutyl ether (C4F9OCH3), ethyl nonafluorobutyl ether (C4F9OC2H5), trans-1,2-dichloroethylene (t-DCE) and isopropanol. This mixture of solvents is a blend of azeotropes. The blend has been analyzed during evaporation and extended use in a vapor degreaser and found to have a consistent composition that is effective for medium- to heavy-duty degreasing and defluxing applications.
Novec 72DA fluid is ideal for a wide range of electronics and other precision cleaning applications. It is intended to replace CFCs, HCFCs, HFCs, nPB and chlorinated solvents. This Novec product has zero ozone depletion potential and other favorable environmental, health and safety properties (see Table 2). The high solvency, low surface tension, nonflammability and stability of Novec 72DA fluid make it ideal for immersion and vapor degreasing applications. The isopropanol in Novec 72DA fluid provides enhanced removal of ionic contaminants.
