Abstract: A process for the manufacture of hydrophobic paper using a pulp comprising a slurry of cellulosic fibers in an aqueous medium comprising an alkoxysilane. A paper or cardboard packaging product comprising cellulosic fibers having a silane residue substantially uniformly distributed throughout the paper or cardboard and bonded to the cellulosic fibers predominantly through Si—O— bonds.

Abstract: Aqueous silane formulations for treatment of an article or material such as wood, concrete, drywall, cotton fabric or wool fabric, and methods of treating the article or material with the formulation. The aqueous medium comprises an alkoxysilane or a combination of a halosilane a high concentration of a salt component. Optionally, the silane formulation may include a boron-containing component. Integrated processes for producing hydrophobic paper, gypsum, drywall, and concrete by pre-mixing components with alkoxysilane are also disclosed. Further disclosed are combinations of a silane component and a salt component, e.g., in a premixture or in a kit, co-pack or co-shipment. Novel treated products, including recreational equipment, are also disclosed.
