Abstract
Compositions containing certain polymeric alkoxysilanes and zinc dust. The polymeric alkoxysilanes comprise a polymer network having the average formula: ##STR1## WHEREIN EACH R is an independently selected hydrocarbon or hydrocarbon ether radical, each R.sup.1 is an independently selected hydrocarbon radical, and all of said radicals are free of aliphatic unsaturation: a has a value from 1 to 3; and b has a value from 0.0001 to 1.0. These polymers are made by reacting an alkoxysilane of the formula ##STR2## WITH WATER AND WITH AN ORGANOSULFONIC ACID OF THE FORMULA R.sub.1 SO.sub.3 H. The compositions are useful for the protection of ferrous surfaces.
