    Abstract: PROBLEM TO BE SOLVED: To provide an aircraft deicing/anti-icing universal fluid excellent in heat stability by incorporating a glycol and/or glycerin, a thickener, a neutralizing agent contg. an alkali metal hydroxide giving a pH in a specified range, a surfactant, and if necessary a corrosion inhibitor, a dye, and water into the same. SOLUTION: This fluid contains 40wt.% or higher glycol and/or glycerin, a neutralizing agent contg. an alkali metal hydroxide in an amt. enough to give a pH of 7.1-9.5, 0.05wt.% or higher thickener, a surfactant associating with the thickener, and if necessary a corrosion inhibitor, a dye, and water. The glycol is selected from among ethylene glycol, propylene glycol, and diethylene glycol. The thickener is a polymer formed from an α,β-ethylenically unsatd. carboxylic acid, an ethylenically unsatd. monomer, a monoethylenically unsatd. macromonomer, and a polyethylenically unsatd. monomer the content of macromonomer-derived parts being 5wt.% or higher. The surfactant is octyl- or nonylphenol ethoxylate.

    Abstract: A glycol- and/or glycerin-based @ universal @ aircraft fluid (i.e., usable as any of Type I, II, III, or IV fluids), and having good resistance to degradation of viscosity and other critical properties caused by exposure to heat and/or shear, is disclosed. The fluid may optionally be prepared as a concentrate, and thereafter significantly diluted in the field for diverse uses. The improved performance is achieved by neutralizing a latex of a hydrophobe-containing, polymeric thickener with a base, preferably an alkali metal hydroxide, and preferably in combination with a weak base such as a salt of a weak acid, and a surfactant which associates with the thickener.
