    摘要： The new agent, based on glycols and water and having crosslinked acrylic polymers as thickener and also customary corrosion inhibitors, surfactants belonging to the group of alkali metal alkylarylsulfonates and neutralizing agent to adjust the pH to a basic value, contains, as the thickener, two selected crosslinked acrylic polymers in a specific ratio by weight to one another, namely a selected crosslinked acrylic acid or alkali metal acrylate homopolymer and a selected crosslinked acrylic acid/acrylamide or alkali metal acrylate/acrylamide copolymer in a ratio by weight of 2 to 10:1 and, as the neutralizing agent, three alkaline compounds, each in a selected amount, namely ammonia, monoethanolamine, diethanolamine and/or triethanolamine as the first alkaline compound, potassium hydroxide as the second alkaline compound and a further alkali metal hydroxide as the third alkaline compound. The new agent exhibits the particular advantage that it has a relatively low viscosity even at arctic temperatures and low shear rates, which ensures rapid and complete run-off of the agent at the take-off of the aircraft even under extreme conditions.

    摘要： A liquid agent for de-icing and protecting against icing-up is described, by means of which it is possible, in particular, to free the metal surface of aircraft rapidly and completely from ice, hoar-frost, snow and the like, and to protect the surface against further build-up for a relatively long period. The agent is essentially composed of several components, namely of (a) glycols, (b) water, (c) thickeners, (d) substances insoluble in water, (e) surface-active agents, (f) corrosion inhibitors and (g) alkaline compounds, in very specific quantities in each case, the quantity of the components (a) and (b) being at least 94%, relative to the total weight of the agent. Its pH value is 7.5 to 10.
