ABSTRACT:
A coolant, comprising an aqueous solution of potassium hydrogencarbonate, a polyhydric alcohol and, where desired, 1.0 to 20.0% by weight of saccharides, which may be additionally incorporated, for the purpose of protection against corrosion, with 0.01 to 0.5% by weight of at least one compound selected from the group consisting of alkali metal salts of silicic acid, alkali metal salts of metasilicic acid and alkali metal salts of polyphosphoric acid.
The coolant has an eutectic melting point as low as -8.5.degree. C. or below and is less corrosive to metal containers. In addition, the potassium hydrogencarbonate in the coolant is quite stable, so that the bubbling phenomenon of the coolant could be prevented.
