Abstract
A multi-component organoalkoxysilane/metal alkoxide sol-gel composition and method for its production are disclosed whereby an organoalkoxysilane of the general formula EQU R.sub.x Si(OR').sub.4-x wherein R is an organic radical, R' is low molecular weight alkyl radical, and x is at least 1 and less than 4, is partially hydrolyzed, reacted with a mixture of metal alkoxides, and the resulting composition is further hydrolyzed and condensed to form an inorganic oxide network. The composition is dried and cured to form an abrasion-resistant coating on a substrate having improved properties in comparison with single metal alkoxide compositions.
