ABSTRACT:
Liquid deicing and anti-icing compositions are provided by aqueous solutions of (a) alkali metal acetates, e.g., KAc or NaAc, (b) phosphate ion, e.g., K.sub.3 PO.sub.4, and (c) soluble silicate, e.g., K.sub.2 SiO.sub.3 or Na.sub.2 SiO.sub.3. These compositions are environmentally safe and meet FAA standards for metal corrosion resistance. They are effective at very low temperatures, e.g. -40.degree. F., and provide particularly effective deicing compositions when used in combination with granular CMA.
