ABSTRACT:
Organotrialkoxysilane stabilizers for inorganic silicate corrosion inhibitor additives in antifreezer/coolant formulations are described. The stabilizers have the following structure: ##STR1## wherein R is an alkyl group of 1-4 carbon atoms, R.sub.1 is either ##STR2## and R.sub.2 and R.sub.3 may be same or different and selected from --Ph, --CN, ##STR3## (wherein R is an alkyl group of 1-4 carbon atoms). These stabilizers help prevent the gelation of the corrosion inhibiting silicate additives in antifreezer/coolant formulations so that the silicates could be more persistent in their corrosion inhibiting properties.
