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.

Abstract: Coolants based on alkylene glycols or derivatives thereof are useful for cooling systems in electric vehicles having fuel cells and/or batteries, preferably for motor vehicles, particularly preferably for passenger cars and commercial vehicles (known as light and heavy duty vehicles). The coolants contain additional corrosion inhibitors for improved corrosion protection in addition to specific azole derivatives.
