# ETI 71DE

ETI 71DE, our Novec 71DE exact-isomer replacement, is a non-flammable, fast-evaporating azeotropic blend of hydrofluoroether (HFE) and trans-1,2-dichloroethylene (t-DCE). It delivers superior cleaning performance for delicate components like electronics, medical devices, or whichever application where Novec 71DE is used. Its low surface tension ensures thorough coverage, while rapid evaporation minimizes downtime. Ideal for high-precision cleaning with no residue left behind.
