Ice Free Switch®

Midwest’s Ice Free Switch anti-icing agent uses a NASA Smart Fluid technology co-developed by NASA/Ames Research Center and Midwest. The patented, licensed technology behind the product enables Ice Free Switch to be poured or sprayed as a liquid which becomes a thin gel-like coating in its activated state.

An anti-icing agent that remains in place and activates when needed

When applied to railroad switch points, plates, rail – and other locations where ice can interfere with operations – before nature dumps snow and freezing rain in subzero temperatures, Midwest’s Ice Free Switch will remain in place and activate when needed. More efficient than rail heaters, it quickly melts falling and blowing snow to prevent switches from freezing ensuring uninterrupted switch operation in freezing temperatures
