ABSTRACT:
Glycol composition useful as antifreeze compositions are prepared containing borates and silicates together with other corrosion inhibitors. The silicates are added to the glycol compositions after the other additives have been added and after the composition has been adjusted to a pH range of 9.5-10.5 in order to give maximum gellation resistance.
