IMPROVED ANTI-ICING COMPOSITION

摘要

An anti-icing composition adapted to prevent ice layers from forming on surfaces where vehicles travel and/or pedestrian walk, such as roads, highways, pavements, airport runways, and the like, and to melt ice layers formed on said surfaces. The composition comprises preferably a first additive, which is a polyhydroxylated compound with at least two hydroxyl groups, such as glycerine, to reduce slipperiness of treated surfaces, and a second additive which is an hydroxyethilamine, in particular commercial or pure triethanolamine, i.e. tris(2-hydroxyethyl)-amine (TEA), to reduce composition corrosiveness. The additive weight percentage of both additive is set between 1 % and 20%, in particular between 2 and 5%, most preferably bout 3%.
