Abstract

See full text

A method and a composition for improving the anti-gel characteristics of antifreeze compositions which contain silicate corrosion inhibitors are disclosed. The anti-gel characteristics are improved through the use of a mercaptosilane of the formula: (SH--R.sub.1).sub.n --Si(R.sub.2).sub.4-n wherein n is 1, 2, or 3, R.sub.1 is branched or straight chain alkyl with 1 to 8 carbon atoms or aromatic with 6 to 10 carbon atoms, and R.sub.2 is a reactive group which will cause the mercaptosilane to form a silanol when hydrolyzed.
