Clearway F1

Based on a formulation of potassium formate and corrosion inhibitors, Clearway F1 is an effective de-icer for airport runways, taxiways and aprons. The product meets not only all relevant environmental and ecological requirements but also the AMS 1435 standard. Clearway F1 is classified WGK1*, both for its excellent biodegradability and because of its low aquatic toxicity. Thanks to these properties, this liquid de-icing solution carries Der Blaue Engel («The Blue Angel») ecolabel.

When applied with the mechanical facilities of airport maintenance departments, Clearway F1 allows snow and ice to be removed quickly and economically.

Clearway F1 melts the ice by depressing the freezing point of water. Due to its low freezing point, the resultant solution will have a much lower freezing point.

*WGK is a German method of classifying chemicals into three (1-3) Water Hazard Classes. Following several tests, the Clearway products have been classified as Class 1: low hazard to waters.
