Ice Free Switch® winter operating switch agent is an anti-icing agent designed to eliminate switch freezing. Applied prior to snow or ice precipitation, it is designed to keep plates, rods, points, flanges, etc., free of snow and ice. Ice Free Switch lubricates plates and movable components and is non-conductive and non-corrosive. Ice Free Switch incorporates NASA developed Zero Gravity Technology so that it is non-newtonian and will stay in place even on vertical surfaces. It works to -70 F and is applied by spraying, pouring or brushing. It is designed to prevent freezing of flanges, springs, movable bridges, signal lenses, door tracks and pockets, and tunnel walls.
