  "title": "Low solids surface coating compositions and use thereof",
  "abstract": "The present invention is directed to low solid surface coating compositions and methods of using the same. The low solid surface coating compositions comprise a self-crosslinking polymer, a solvent, a surfactant, and water. The low solid surface coating compositions can preferably have a total solid content of less than 15%.",
  "claims": [
    "1. A method of treating a surface comprising: applying by spraying with a robotic floor coating device a composition comprising between about 1 wt-% and about 15 wt-% of a polymer; wherein said polymer comprises a self-crosslinking polyurethane polymer; between about 0.01 wt-% and about 1.7 wt-% of a solvent; between about 0.01 wt-% and about 1 wt-% of a surfactant; and between about 70 wt-% and about 98.98 wt-% of water, wherein said composition has a viscosity of 15 cps or less, wherein said composition has a solid content of between 5 wt-% and less than 8 wt-%, a shelf life of at least 6 months, and forms a stable and even film without uneven leveling after being applied by spraying to a surface one or more times without a leveling process.",
    "2. The method of claim 1, wherein said surface is a floor.",
    "3. The method of claim 1, further comprising allowing the composition to dry.",
    "4. The method of claim 3, further comprising reapplying the composition.",
    "5. The method of claim 1, wherein said composition has a viscosity of 10 cps or less.",
    "6. The method of claim 1, wherein said solvent comprises a glycol ether.",
    "7. The method of claim 1, wherein said surfactant comprises an organo-fluorine, silicone-based surfactant, and/or silicone emulsion or colloid.",
    "8. The method of claim 1, wherein said solvent comprises mono butyl ether, and wherein said surfactant comprises a siloxane.",
    "9. The method of claim 1, wherein said solvent comprises between about 0.05 wt-% and about 1 wt-% of the composition.",
    "10. The method of claim 1, wherein the composition has a viscosity of 7 cps or less.",
    "11. The method of claim 1, wherein said composition has a shelf life of at least one year.",
    "12. The method of claim 1, said composition further comprising at least one of the following additional functional ingredients: a leveling agent, a wax, a fragrance, a dye, a polish, a corrosion inhibitor, a plasticizer, a fungicide, a biocide, a friction modifier, a metal complex, a rheology modifier, or a thickener.",
    "13. A method of treating a surface comprising: applying by spraying with a robotic floor coating device a composition comprising between about 1 wt-% and about 15 wt-% of a polymer, wherein said polymer comprises a self-crosslinking polyurethane polymer; between about 0.1 wt-% and about 1 wt-% of a solvent; between about 0.07 wt-% and about 0.5 wt-% of a surfactant; and between about 70 wt-% and about 98.98 wt-% of water; wherein said composition has a viscosity of 15 cps or less, wherein said composition has a solid content of between 5 wt-% and less than 8 wt-%, a shelf life of at least 6 months, and forms a stable and even film without uneven leveling after being applied by spraying to a surface one or more times and without a leveling process.",
    "14. The method of claim 13, wherein said solvent comprises a glycol ether, and wherein said surfactant comprises an organo-fluorine, silicone-based surfactant, and/or silicone emulsion or colloid.",
    "15. The method of claim 13, wherein said polymer comprises between about 5 wt-% and about 10 wt-% of the composition, and wherein said solvent comprises between about 0.5 wt-% and about 1 wt-% of the composition.",
    "16. The method of claim 13, wherein the composition has a viscosity of 7 cps or less; and/or a shelf life of at least 1 year.",
    "17. The method of claim 13, wherein said surface is a floor.",
    "18. The method of claim 13, further comprising reapplying the composition."
