Abstract
A composition is formed by combining water with an organic polymer such as polybutylene or an alkyd resin, and an alkoxysilane of the formula R.sub.n Si(OR').sub.4-n where R is an alkyl radical of 1-10 carbon atoms, an alkenyl radical having 2-8 carbon atoms, phenyl, chloropropyl, or trifluoropropyl, n is 1 or 2, and R' is an alkyl radical having 1-6 carbon atoms. The composition is free of amine or quaternary ammonium functional silanes. It can be emulsified and used to treat a cellulosic or masonry surface to render it water repellent.
