# ETI 71DA

ETI 71DA, Novec 71DA exact-isomer replacement, is a non-flammable, fast-drying azeotropic blend of hydrofluoroether (HFE), trans-1,2-dichloroethylene (t-DCE), and alcohol. It provides efficient precision cleaning and degreasing for sensitive components, including electronics and optics. This solvent offers excellent solvency, low surface tension for effective wetting, and rapid evaporation with no residue, making it suitable for high-performance applications or wherever Novec 71DA is used.
