<p>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 acetate, Clearway 6s is an effective solid runway de-icer with low environmental impact. It has a moderately corrosive effect on zinc, galvanized material, solder and soft solders. We therefore recommend that these materials be avoided.</p> <p>Clearway 6s 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 not only meets all the relevant environmental and ecological requirements but also the AMS 1431 standard. Clearway 6s is classified WGK1* both for its biodegradability and because of its low aquatic toxicity.</p> <p>When applied with the mechanical facilities of airport maintenance departments, Clearway 6s 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>
