Product Description
FC-70 belongs to the 3M Fluorinert family: a fully fluorinated liquid, clear and colourless, with no flash point at all. Thermal and chemical stability hold up over time, sensitive materials tolerate it, and what evaporates leaves essentially nothing behind — useful for moving heat and for running vapour phase soldering. Its vapour is heavy and stays where it is put, displacing oxygen and making mild fluxes workable.
