Liquid Deicer

New River Gorge Bridge - WV

CF7® liquid deicer is a high performing 50% aqueous potassium acetate solution, by weight, with less than 1% corrosion inhibitors. CF7 is non-chloride based making it safer for structural steel and reinforcing steel embedded in concrete. CF7 is a clear, colorless, mobile liquid, free from matter in suspension. It is effective at low temperatures, -25°F (-32°C) and is stable in storage with no agitation required.

Potential CF7 customers typically include, but are not limited to, DOT's, public works agencies, property management firms, and industrial firms. Customers concerned with deicing performance, environmental issues, and corrosion choose CF7 as a cost effective solution to their concerns.

CF7 is best used as an anti-icer, sprayed on the pavement before precipitation starts but can also be used as a deicer. CF7 is very effective as a prewetting agent for solid deicers such as Cryotech CMA®, Cryotech NAAC®, road salts, and sand. Due to its low freeze point, -76°F (-60°C), CF7 significantly improves the performance of solids. Because it is a clear liquid free from matter in suspension with low viscosity, it does not clog spray nozzles, even at very low temperatures.


  • Non-chloride based
  • Very low corrosion to steel
  • Liquid formulation works fast, on contact
  • Easy to handle, no agitation required
  • Can be used for anti-icing, deicing, and prewetting solid
  • Good tire tracking
  • Low viscosity, not slippery
  • Complimentary customer training upon request


  • Has low freeze point of -76°F (-60°C)
  • Effective to -25°F (-32°C)
  • When used as an anti-icer, CF7 prevents bonding of snow/ice to pavement
  • When used as a deicer, CF7 breaks snow/ice bonds prior to mechanical removal
  • Does not refreeze as fast as common deciers, the residual effect requires fewer applications


  • Non-persistent, readily biodegrades at low temperatures
  • Low BOD and toxicity to fish, mammals, and vegetation
  • Does not contain nitrogen or chlorides
  • Recognized as "relatively harmless" by the U.S. Fish and Wildlife scale


  • Application rates vary considerably based on pavement temperatures, forecast, traffic action, and level-of-service expectations
  • In general, apply as you would salt brine. However, CF7 can be used at much lower temperatures
  • CF7 is best applied early or right before a storm as an anti-icer to prevent ice bonding to the pavement surface
  • CF7 can also be used at the spreader as a prewetting agent to accelerate solid deicers such as Cryotech NAAC® or salt.
