ABSTRACT:
Stabilizers for inorganic silicate corrosion inhibitor additives in antifreeze/coolant formulations are described. The stabilizers have the structure ##STR1## where n is an integer from 1 to 20 and R is a solubilizing agent. The solubilizing group may be a cyano-terminated group, a diol ether group, an acid group, an amide group, a group which will yield a diol on hydrolysis, among others. These stabilizers help prevent the inorganic silicate additives from precipitating out and thus extend the shelf life of antifreeze formulations into which they are incorporated.
