Eastman’s de-icers are marketed under the brand name Clearway®. Clearway is acknowledged as one of the leaders in airport runway de-icing and the product range has been developed and expanded to include both liquid and solid formate-based and acetate-based products.
Based on sodium formate, Clearway SF3 is an effective solid runway de-icer with low environmental impact. Clearway SF3 melts ice by depressing the freezing point of water and is active at temperatures to -15°C. The irregular-shaped granules will remain where spread. We advise to use the product pre-wetted in combination with corresponding liquid Clearway de-icers to obtain a rapid initial de-icing effect; it can also be applied alone to give a long residual anti-icing effect under extreme weather conditions.
The product meets not only all relevant environmental and ecological requirements but also the AMS 1431 standard. Clearway SF3 is classified WGK1*, both for its excellent biodegradability and because of its low aquatic toxicity. Thanks to these properties, this solid de-icing solution carries the Blaue Engel (‘Blue Angel’) ecolabel.
When applied with the mechanical facilities of airport maintenance departments, Clearway SF3 allows snow and ice to be removed quickly and economically.
*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.
