Abstract

The present invention relates to an aqueous based silicone protectant composition and method for treating various solid surfaces including, but not limited to, fiber-based products, leather, or other soft or hard surfaces to impart water and stain repellency. The protectant composition comprises an MQ resin, a polyorganosiloxane fluid, a silicone solvent and water. The aqueous silicone-based protectant composition is hydrophobic and substantially free of surfactants. The protectant composition can be applied directly or indirectly to a solid surface using various application devices including, but not limited to, spray, aerosol, wipes, sponges and pads.

Claims (33)

1. An aqueous composition consisting of:

a. an MQ resin;

b. a polydimethylsiloxane fluid;

c. a VOC exempt silicone solvent;

d. water; and

e. optionally, an adjunct selected from the group consisting of: fragrances, dyes, swellable polymers, abrasives, aerosol propellants, and combinations thereof;

wherein the aqueous composition forms an aqueous water-in-oil gel.

2. The aqueous composition of claim 1 , wherein the viscosity of the composition ranges from about 1,000 to 10,000 cP at 25° C.

3. The aqueous composition of claim 1 , wherein the composition comprises about 0.1 to 5% by weight of MQ resin.

4. The aqueous composition of claim 1 , wherein the composition comprises about 0.2 to 10% by weight of polydimethylsiloxane fluid.

5. The aqueous composition of claim 1 , wherein the composition comprises about 1 to 18% by weight of a VOC exempt silicone solvent.

6. The aqueous composition of claim 1 , wherein the composition comprises an adjunct which less than 1% by weight of swellable hydrophobically modified polymers.

7. The aqueous composition of claim 1 , wherein the pH of the composition ranges from about 6 to 8.

8. The aqueous composition of claim 1 , wherein the VOC exempt silicone solvent comprises a volatile methylsiloxane fluid.

9. The aqueous composition of claim 1 , wherein the MQ resin is a trimethylsilicate resin containing a silanol group.

10. An upholstery and carpet treating composition consisting of: an aqueous emulsion of a silanol-functional MQ resin, a polydimethylsiloxane fluid, and water.

11. The aqueous composition of claim 10 , wherein the viscosity of the composition ranges from about 1,000 to 10,000 cP at 25° C.

12. The aqueous composition of claim 10 , wherein the composition comprises about 0.1 to 5% by weight of the silanol-functional MQ resin.

13. The aqueous composition of claim 10 , wherein the composition further comprises about 0.2 to 10% by weight of polydimethylsiloxane fluid.

14. The aqueous composition of claim 10 , wherein the pH of the composition ranges from about 6 to 8.

15. An aqueous composition consisting of:

a. about 0.1-5% by weight of one or more silanol-functional MQ resins;

b. about 0.2-10% by weight of one or more polydimethylsiloxane fluids;

c. about 1-18% by weight of one or more volatile methylsiloxane VOC-exempt solvents; and

d. at least 70% by weight of water.

16. A method for protecting surfaces comprising the steps of:

a. treating a surface with a protective composition consisting:

i. one or more MQ resins;

ii. one or more polyorganosiloxane fluids;

iii. one or more VOC exempt silicone solvents; and

iv. water

b. allowing the water in the protective composition to evaporate or manually drying the surface treated with the protective composition; and

c. forming a resulting protective coating on the surface which is essentially free of solvent.
