3M Novec 72DE Engineered Fluid Medium-Heavy Degreasing Solvent
Type: Azeotropic Blend
Boiling Point: 43°C
KB Value: 52
Surface Tension: 19.0 dynes/cm
Packing: 5 kg / 20 kg drum
3M Novec 72DE Engineered Fluid is a high-solvency azeotropic blend of methyl nonafluorobutyl ether (10%), ethyl nonafluorobutyl ether (20%), and trans-1,2-dichloroethylene (70%). Formulated for medium- to heavy-duty degreasing applications, this clear, colorless, nonflammable fluid delivers exceptional cleaning performance in industrial and electronics manufacturing. With a Kauri-Butanol (KB) value of 52 — significantly higher than Novec 71DE (KB 27) — Novec 72DE provides superior solvency for removal of heavy oils, greases, waxes, and tough soils from complex metal and plastic assemblies.
Novec 72DE offers a unique combination of properties: low surface tension (19.0 dynes/cm) for excellent wetting and penetration, azeotropic behavior with consistent boiling composition at 43°C, and zero ozone depletion potential with a GWP of 435. The blend of HFE-7100 and HFE-7200 provides optimized cleaning performance for a wide range of soils, while the high t-DCE content (70%) delivers enhanced solvency for challenging degreasing applications. With t-DCE not classified as a Hazardous Air Pollutant (HAP), Novec 72DE offers a favorable regulatory profile compared to traditional chlorinated solvents, making it an ideal replacement for CFC-113, HCFC-141b, HCFC-225, trichloroethylene, perchloroethylene, and nPB in vapor degreasing, immersion cleaning, and specialty solvent applications.
