  • Method of treating surfaces with organosilicon water repellent compositions
    Patent number: 6403163
    Abstract: A composition for rendering surfaces water repellent is formed by combining water or a solvent; a methylhydrogensiloxane polymer or copolymer; an alkoxysilane having the formula RaSi(OR′)4−a in which R represents an alkyl group containing 1-10 carbon atoms, an alkenyl group containing 2-8 carbon atoms, an aryl group, or an haloalkyl group, a has a value of 1 or 2, and R′ represents an alkyl group containing 1-6 carbon atoms; and a silicone resin. The composition can also contain other components such as a volatile methyl siloxane, a cationic oil-in-water emulsion of an aminofunctional polydimethylsiloxane, a surfactant, a catalyst, a beading agent, an organic wax, a preservative, an antifoam, a mildewcide, an UV absorber/UV light stabilizer, or a freeze-thaw additive.
