描述
3M Novec 72DA Engineered Fluid Medium-Heavy Degreasing Defluxing Solvent
Type: Azeotropic Blend
Boiling Point: 44°C
KB Value: 58
Surface Tension: 18.0 dynes/cm
Packing: 5 kg / 20 kg drum
3M Novec 72DA Engineered Fluid is a high-solvency azeotropic blend of methyl nonafluorobutyl ether (10%), ethyl nonafluorobutyl ether (20%), trans-1,2-dichloroethylene (68%), and isopropanol (2%). Formulated for medium- to heavy-duty degreasing and defluxing applications, this clear, colorless, nonflammable fluid delivers exceptional cleaning performance in electronics and precision manufacturing. With a Kauri-Butanol (KB) value of 58 — significantly higher than Novec 71DA (KB 33) — Novec 72DA provides enhanced solvency for removal of resin solder flux residues, heavy oils, greases, and waxes from complex assemblies.
Novec 72DA offers a unique combination of properties: low surface tension (18.0 dynes/cm) for excellent wetting and penetration, azeotropic behavior with consistent boiling composition at 44°C, and zero ozone depletion potential with a GWP of 435. The isopropanol component enhances removal of ionic contaminants, while the blend of HFE-7100 and HFE-7200 provides optimized cleaning performance for a wide range of soils. With t-DCE not classified as a Hazardous Air Pollutant (HAP), Novec 72DA offers a favorable regulatory profile compared to traditional chlorinated solvents, making it an ideal replacement for CFCs, HCFCs, HFCs, nPB, and chlorinated solvents in vapor degreasing and immersion cleaning applications.
