Abstract: A corrosion-inhibited heat transfer composition concentrate comprising an alcohol, an organosiloxane/silicate copolymer, and a corrosion inhibiting amount of a nitrate salt. Such coolant concentrate may suitably be diluted with from about 25% to about 90% by weight of water based upon the weight of the concentrate, to form an aqueous composition which has particular utility as a corrosion-inhibited heat transfer composition for heat exchange systems, for example, those employed with internal combustion engines. Such compositions are highly effective in reducing corrosion in heat exchange systems containing components of aluminum construction.
