FIELD: chemistry.
SUBSTANCE: present invention is aimed at stabilised transfer-transfer aqueous compositions, which contain silicon dioxide nanoparticles. Invention also covers use of concentrate, as well as dilution of concentrate. Composition includes at least one type of colloidal silicon dioxide particles, wherein each particle has an average particle diameter in range from 0.1 to 1,000 nm, at least one type of a silicate with a phosphonate functional group and at least one type of metal corrosion inhibitor.
EFFECT: technical result is obtaining an aqueous heat transfer solution, having improved stability, as well as heat conductivity, which also provides protection from corrosion.
