Organosilane stabilizers for inorganic silicates in antifreezer/coolant compositions

摘要

Organotrialkoxysilane stabilizers for inorganic silicate corrosion inhibitor additives in antifreezer/coolant formulations are described. The stabilizers have the following structure; <IMAGE> wherein R is an alkyl group of 1-4 carbon atoms, R1 is either <IMAGE> and R2 may be selected from <IMAGE> and R3 is phenyl or <IMAGE> These stabilizers help prevent the gelling of the corrosion inhibiting silicate additives in antifreezer/coolant formulations thereby increasing the useful lifetime of such formulations.
