3M Novec 72DE engineered fluid is an azeotropic precision cleaning solvent formulated from hydrofluoroether (HFE) and trans-1,2-dichloroethylene (t-DCE), designed for heavy-duty vapor degreasing and immersion cleaning to remove flux, oils, low-melting waxes, lubricants and hydraulic fluids.
With a boiling point of 44 °C and a liquid density of 1.28 g/cm³ at 25 °C, 3M Novec 72DE engineered fluid is a near-azeotropic blend whose vapor and liquid compositions remain essentially constant at the boiling point, keeping its properties stable over long-term use in various vapor degreaser types.
3M Novec 72DE engineered fluid has a Kauri-Butanol (KB) value of 52, offering strong solvency to effectively remove rosin flux residue, greases, waxes and particulates; its low surface tension (19 dynes/cm) allows penetration into tight gaps and complex geometries, drying quickly with no residue and high cleaning yield.
3M Novec 72DE engineered fluid is compatible with most metals such as aluminum, copper, carbon steel, stainless steel, titanium and tantalum, as well as solvent-resistant plastics and elastomers. It is widely used in aerospace, microelectronics, medical devices, precision optics, disk and hard-drive manufacturing and precision metal part production, and is also suitable for oxygen system cleaning and coating or lubricant deposition.
3M Novec 72DE engineered fluid is a high-performance azeotropic cleaning fluid that replaces trichloroethylene (TCE), n-propyl bromide (nPB) and certain CFC/HCFC/HFC and chlorinated solvents, delivering strong solvency with a better safety and environmental profile to meet the cleaning quality and environmental compliance needs of precision electronics and aerospace parts.
