A protective coating for organic substrates includes an emulsion having a branched trimethylsilylated alkylsilsesquioxane. The trimethylsilylated alkylsilsesquioxane has the formula:wherein R is a substituted or unsubstituted linear or branched monovalent hydrocarbon substituent with from 6 to 14 carbon atoms, Me is Methyl, and x ranges from 1 to 6. Also disclosed is a method of rendering an organic surface repellent to water, dust and dirt by treating the organic surface with an effective amount of the foregoing emulsion. The organic surface being treated can be a rubber surface such as wires, cables, the sidewall of automotive tires, footwear, and coated fabrics. The surface can also be a synthetic plastic surface such as automotive dashboards, automotive trim (both interior and exterior), automotive upholstery, flooring, residential siding, and piping. |
