Claims
- 1. A rubber or vinyl protectant composition comprising (A) a silicone component selected from the group consisting of (i) an aqueous emulsion containing a polysiloxane stabilized in the emulsion by a nonionic surfactant, the polysiloxane in the emulsion having a particle diameter greater than 140 nanometers (0.14 micrometer) and less than 350 nanometers (0.35 micrometer), (ii) an aqueous emulsion containing an emulsion polymerized polysiloxane stabilized in the emulsion by a nonionic surfactant and an ionic surfactant, the polysiloxane in the emulsion having a particle diameter greater than 140 nanometers (0.14 micrometer), and (iii) an aqueous microemulsion containing an emulsion polymerized polysiloxane stabilized in the microemulsion by a nonionic surfactant and an ionic surfactant, the polysiloxane in the microemulsion having a particle diameter less than 140 nanometers (0.14 micrometer); and (B) an acrylic component selected from the group consisting of acrylic polymer emulsions, acrylic polymer solutions, acrylic polymer colloidal solutions, acrylic polymer dispersions, and acrylic polymer colloidal dispersions; the acrylic component and the silicone component being blended together to yield a polysiloxane/acrylic polymer ratio of 25:75 to 75:25 on a weight basis.
- 2. A composition according to claim 1 in which emulsion (A)(i) contains 20-60% by weight of polysiloxane, 0.01-15% by weight of nonionic surfactant, based on the weight of the emulsion, the balance water; and emulsion (A)(ii) and microemulsion (A)(iii) contain 10-70% by weight of polysiloxane, 0.5-30% by weight of nonionic surfactant, 0.05-30% by weight of ionic surfactant, based on the weight of the emulsion and the microemulsion, respectively, the balance water.
- 3. A composition according to claim 2 in which the nonionic surfactant in emulsion (A)(i) is an ethoxylated alcohol; and the acrylic component in the protectant composition is an acrylic polymer emulsion containing a terpolymer formed from (i) an olefinically unsaturated carboxylic acid monomer, (ii) an acrylate or methacrylate ester monomer, and (iii) an unsaturated aromatic monomer.
- 4. A composition according to claim 3 in which the acrylic polymer emulsion contains a butylacrylate/styrene/methacrylic acid terpolymer.
- 5. A composition according to claim 2 in which the nonionic surfactant in emulsion (A)(ii) and microemulsion (A)(iii) is a polyoxyethylene fatty alcohol; the ionic surfactant is an alkylarylsulfonate having one or more alkyl groups of 8 or more carbon atoms; and the acrylic component in the protectant composition is an aqueous solution containing 30% by weight of an acrylic polymer based on the weight of the solution.
