ANTI-ICING COMPOSITIONS AND METHODS FOR APPLICATION THEREOF Russian patent published in 2004 - IPC

FIELD: special-destination fluids. SUBSTANCE: aim of invention is to suppress icing and to reduce ice on a variety of surfaces, in particular on runway and on aircrafts. For that aim, invention provides composition containing succinate salt (1-10%) and sodium polyaspartate at weight ratio between 90:10 and 99:1 supplemented by sodium or calcium chloride. Succinate salt can be in particular potassium succinate, magnesium succinate, or their mixture at weight ratio between 97:3 and 95:5. Composition containing potassium succinate and sodium polyaspartate may further contain polymaleimide salt. EFFECT: enhanced anti-icing capacity, reduced corrosive effect of sodium chloride more than be 50%, and inhibited corrosion of steal, aluminum, and magnesium alloys. 20 cl, 15 dwg, 15 ex
