Abstract

A method of improving the water repellency of a cellulosic web, such as paper, involves treating the web with an alkyl alkoxysilane containing at least one methyl group and at least two lower alkoxy (1-2c) groups in the presence of a condensation catalyst, and curing the resulting treated web for a time sufficient to increase the water repellency thereof. The treatment can be carried out in the presence of a solvent or in the absence of a solvent.
