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.
Claims16
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.
An upholstery and carpet treating composition consisting of:
- an aqueous emulsion of a silanol-functional MQ resin, a polydimethylsiloxane fluid, and water.
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.
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.
