Abstract
Abstract A composition for waterproofing and inhibiting corrosion of silicon dioxide containing substrates, such as masonry structures. The composition is from about 7% by weight to about 60% by weight of an alkylalkoxysilane, including oligomers and mixtures thereof, having a molecular weight of from about 100 to about 1000, and a solvent for the silane which can be an aromatic or aliphatic hydrocarbon solvent or mixtures thereof, with the solvent being free of alcohol groups.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
99 words
A composition for waterproofing and inhibiting erosion and corrosion of silicon dioxide containing substrates, such as masonry structures, steel reinforced masonry structures and the like, comprising: from about 7% by weight to about 60% by weight of an alkylalkoxysilane including oligomers and mixtures thereof, having a molecular weight of from about 100 to about 1000; and a solvent for said silane, selected from the group consisting of C 6 to C 10 aromatic and cyclic hydrocarbons, or mixtures thereof, said solvent being free of alcohol groups and having a flash point of from 100° F. to about 160° F.
Claim 2
Dependent Claim
