ABSTRACT:
Compositions useful for providing water repellent characteristics to substrates contain (i) 0.1-99 percent by weight of a methylhydrogensiloxane; (ii) 0.1-99 percent by weight of a silanol endblocked siloxane; (iii) 0.1-99 percent by weight of a silicone resin; (iv) 0.1-10 percent by weight of at least one surface active agent; and (v) 0.01-5 percent by weight of at least one additive selected from the group consisting of a preservative, an antifoam, a mildewcide, a UV absorber/UV light stabilizer, and a freeze-thaw additive. The balance of the composition to 100 percent by weight is water.
