FIELD: chemistry.
SUBSTANCE: concentrate contains the following in wt %: C1-C3 monoatomic alcohol 52.5-80.0, diatomic alcohol from the family of glycols as a water-soluble depressant 8.0-20.0, glycerine 8.0-27.0 and a packet of inhibiting additives - not more than 5.0. Said concentrate ensures efficient reduction of the temperature of liquid coolants when used in ratio to the liquid coolant of 1:6-16.
EFFECT: improved temperature characteristics while preserving all the other parameters of liquid coolants by reducing the chilling point.
