Abstract: An aqueous silane composition for increasing the resistance to penetration by aqueous media of an absorbent substrate is disclosed. The compositions are made from effective amounts of ingredients that initially include: a hydrolyzable silane; a low molecular weight silicone; an amino-functional silicone; an amino-functional silane; and the balance of water. The aqueous silane compositions are characterized by increased shelf-life, increased depth of penetration; and the ability to be made in high concentrations that facilitate lower shipping costs, while at the same time, being dilutable for application to masonry.

Abstract: There are provided aqueous, heat curable compositions useful in the finishing of textile fabrics, the compositions comprising a diisophorone alkylene urea ethoxylate, a silanol end-stopped diorganopolysiloxane and a diorganopolysiloxane having an amino functionality. In preferred embodiments, the compositions also comprise a compound selected from among dimethylol dihydroxyethylene urea and dimethylol methoxy ethyl carbamate. The compositions, when applied to textile fabrics, result in improved wettability and soil releasability, without losses in hand modification and resistance to abrasion. Processes and articles are also provided.
