Abstract: Antifreeze concentrate with corrosion protection which is suitable for coolants and heat transfer fluids and comprises freezing point-lowering liquids and also particular sulfur-comprising organic compounds, inorganic molybdate salts, inorganic phosphate salts and aliphatic, cycloaliphatic or aromatic monocarboxylic, dicarboxylic or tricarboxylic acids as corrosion inhibitors. Aqueous coolant compositions which are suitable for cooling an internal combustion engine whose cooling apparatus has been made of aluminum using a soldering process using a fluoroaluminate flux can be obtained therefrom.

Abstract: Novel aqueous coolants with improved temperature stability contain (A) water; (B) at least one alkylene glycol, alkylene glycol monoalkyl ether, or glycerol; (C) at least one phosphate, carbonate, and/or sulfate in the form of its free acids or its salts; (D) at least one hard water stabilizer; and optionally, further inhibitors and typical coolant constituents. The aqueous coolants are useful, for example, in internal combustion engines.
