Abstract
An aqueous silane composition for increasing the resistance to penetration by aqueous media of an absorbent substrate. The composition includes about 1.7 wt. % of an emulsion of an amino functional silicone having an amine content of about 70 mg KOH/gm; up to about 80 wt. % of a hydrolyzable silane; up to about 5 wt. % of an amino functional silane; and the balance water. The resulting composition is hydrolytically stable for a long period without requiring a separate buffering compound while, at the same time, may be prepared in much higher concentrations to reduce packaging and shipping costs.
