ABSTRACT:
An antifreeze concentrate comprising an alcohol, buffer, silicate, and a silicate protecting agent comprising an alkane tetracarboxylic acid, preferably a 1, 2, 3, 4-alkane tetracarboxylic acid, and derivative thereof. The antifreeze concentrate may suitably be diluted with from about 10% to about 90% by weight of water based upon the weight of the concentrate, wherein the water may contain hard water cations without significant loss of soluble silicate species. The aqueous antifreeze compositions have particular utility as a composition for heat exchange systems, for example, those employed with internal combustion engines.
