Abstract
Compositions having improved sability which, when applied to a variety of substrates and cured, form transparent coatings having superior abrasion resistant properties. The coating compositions are aqueous-organic solvent mixtures containing a mixture of hydrolysis products and partial condensates of an epoxy functional silane and a tetrafunctional silane and a multifunctional compound selected from the group consisting of multifunctional carboxylic acids, multifunctional anhydrides and combinations thereof.
