Deicing and anti-icing composition for aircraft

摘要

A deicing and anti-icing composition for aircraft surfaces including a base compound being propylene glycol and/or ethylene glycol in the range of 35.0 % to 80.0 % by weight of the deicing and anti-icing composition. A diluent is included in the form of water for use as a carrier fluid for the glycol. A first molecular weight non-ionic surfactant agent is included having an HLB in the range of 4 to 17, and a second molecular weight non-ionic surfactant agent is included having an HLB in the range of 5 to 18. The second non-ionic surfactant agent has an HLB at least two (2) units higher than the first non-ionic surfactant agent. An emulsifier is included in the form of a polycarboxylate compound being in the range of 1 ppm to 0.5 % by weight of the deicing and anti-icing composition. A pH control agent maintains the pH of the deicing and anti-icing composition between a 6 and 10 value.
