Abstract

A vehicle surface treatment composition includes a colloidal inorganic oxide dispersion or a soluble silicate amenable to application to both porous and semi-porous vehicle hard surfaces to provide a multi-surface protective barrier that imparts water repellency and weathering protection properties to the vehicle finish. The composition provides a hard surface cleaning and forms a coating to the applied surface. The compositions provide treated surface properties that include keeping clean, scratch/mar defense, bug repellency, UV protection, and weathering defense. The compositions create treated surfaces that are highly smooth and lubricious which provide enhanced protection, while achieving a high luster finish with a streak free appearance. The composition is readily applied through resort to a conventional trigger spray application, propellant aerosol, or a sponge or cloth for wipe application onto the vehicle surface.

First claim

The invention claimed is:

1. A vehicle surface treatment composition comprising:
a colloidal inorganic oxide dispersion; and
a self-emulsifying silicone emulsion with which said colloidal inorganic oxide dispersion and a wetting agent form a clear suspension, said wetting agent being a non-ionic polymeric fluorochemical surfactant, a fluoroaliphatic polymeric ester in a hydrocarbon solution, a polyfluoroalkyl betaine amphoteric surfactant, a nonionic polymeric fluorinated surfactant, an anionic phosphonated fluorinated surfactant, a nonionic ethoxylated fluorinated surfactant, or a combination thereof, said wetting agent present from 0.05 to 4 total weight percent, the vehicle surface treatment forming a smooth and uniform coating on a vehicle surface with an initial shine of from 90 to 230 gloss units.

2. The surface treatment composition of claim 1 , wherein said silicone emulsion is present, elastomeric and has a weight average molecular weight of between 100,000 and 2,000,000.

3. The surface treatment composition of claim 1 , wherein said colloidal inorganic oxide dispersion is a silica dispersion.

4. The surface treatment composition of claim 1 , wherein said colloidal inorganic oxide dispersion is titanium dioxide or zirconium dioxide.

5. The surface treatment composition of claim 1 , wherein said colloidal inorganic oxide dispersion is stabilized by either electrostatic stabilization or steric stabilization.

6. The surface treatment composition of claim 1 , wherein said colloidal inorganic oxide dispersion has a mean particle size of between 1 to 500 nm.

7. The surface treatment composition of claim 1 , wherein said colloidal inorganic oxide dispersion has a particle size of between 2 to 100 nm.

8. The surface treatment composition of claim 1 , wherein said colloidal inorganic oxide dispersion has a viscosity in a range from 3 cPs to 20 cPs and with a density range from 1.10 to 1.30 g/ml.

9. The surface treatment composition of claim 1 , further comprising a soluble silicate.

10. The surface treatment composition of claim 1 , further comprising a defoamer.

11. The surface treatment composition of claim 10 , wherein said defoamer is a polysiloxane.

12. The surface treatment composition of claim 1 , further comprising polysilazanes.

13. The surface treatment composition of claim 1 , wherein the initial shine is from 100 to 230 gloss units.

14. A method of forming a coating comprising:
applying the composition of claim 1 to a vehicle exterior component; and
allowing the composition to dry to form the coating.
