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.</p> <p>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.</p> <p>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.</p> <p>When applied with the mechanical facilities of airport maintenance departments, Clearway SF3 allows snow and ice to be removed quickly and economically.</p> <p><i>*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.</i></p>
