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 a formulation of potassium acetate and corrosion inhibitors, Clearway 1 has been on the market for nearly 30 years as an effective liquid runway de-icer with low environmental impact.
The product meets not only all relevant environmental and ecological requirements but also the AMS 1435 standard. Clearway 1 is classified WGK1* both for its biodegradability and because of its low aquatic toxicity.
When applied with the mechanical facilities of airport maintenance departments, Clearway 1 allows snow and ice to be removed quickly and economically.
Clearway 1 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.
