Abstract
Improved deicing compositions and methods are provided. In particular, the subject invention is directed at deicing compositions which are suitable and effective for airport applications in which corrosion of magnesium based alloys is an issue. In particular, the invention is directed at deicing compositions which are less corrosive of steel and aluminum and certain magnesium based parts than conventional road salt. For example, the invention is directed to deicing compositions which are substantially less corrosive than allowed for use on aircraft metal parts, such as magnesium based alloys unlike acetate and formate salts. The subject invention is also directed at deicing compositions which inhibit the corrosive effects of conventional road salt. The subject invention is also directed at deicing compositions comprising effective deicing amounts of succinate salts, such as potassium succinate (trihydrate), ammonium succinate (anyhdrous), sodium succinate (hexahydrate), either alone or in combination. The subject invention is also directed at deicing compositions comprising effective corrosion inhibiting, deicing amounts of potassium succinate together with effective amounts of 1) polymaleimide sodium salt and magnesium succinate, 2) magnesium succinate and sodium polyaspartate, 3) sodium polysuccinimide, 4) sodium polyaspartate and polymaleimide sodium salt, 5) magnesium succinate or 6) sodium chloride which will enhance deicing and/or corrosion inhibiting properties.
