# ETI 73DE

ETI 73DE, our Novec 73DE exact-molecule replacement, is a non-flammable, fast-evaporating azeotropic blend of hydrofluoroether (HFE) and trans-1,2-dichloroethylene (t-DCE). It offers outstanding cleaning efficiency for critical applications such as electronics, optics, and medical devices. With excellent solvency, low surface tension, and rapid evaporation, it leaves no residue, making it ideal for high-performance precision cleaning wherever Novec 73DE is used.
