Abstract

Disclosed herein is a winter precipitation barrier composition, comprising: a retaining agent, a solvent, and optionally, an auxiliary component, such as a rheology/viscosity modifier, surfactant, detergent, foaming/defoaming additive, humectant, dye, colorant, fragrance, or a combinations thereof. In one embodiment, the retaining agent comprises a primarily hydrophobic monomer or a hydrophilic monomer.

Claims (16)

1. A winter precipitation barrier composition comprising

a retaining agent comprising an ethylene oxide/propylene oxide copolymer; and

a solvent comprising a mixture of a monoalcohol and ethylene glycol.

2. The winter precipitation barrier composition of claim 1 , wherein the composition further comprises at least one of a silicone oil, fluorinated polyether diol, rheology/viscosity modifier, surfactant, detergent, foaming/defoaming additive, humectant, dye, colorant, fragrance, and combinations thereof.

3. The winter precipitation barrier composition of claim 1 , wherein the monoalcohol is methanol.

4. The winter precipitation barrier composition of claim 1 , wherein the retaining agent comprises a copolymer comprising ethylene oxide, propylene oxide, and glycerol.

5. The winter precipitation barrier composition of claim 1 , wherein the retaining agent comprises a polymer or copolymer having a molecular weight of from about 2500 unified atomic mass units to about 2700 unified atomic mass units.

6. The winter precipitation barrier composition of claim 1 , wherein the retaining agent comprises a polymer or copolymer having a the molecular weight of from about 2,000 unified atomic mass units to about 3,000 unified atomic mass units.

7. The winter precipitation barrier composition of claim 1 , wherein the retaining agent comprises a polymer or copolymer having a molecular weight of about 2600 unified atomic mass units.

8. The winter precipitation barrier composition of claim 1 , wherein the composition has a freezing point of less than 0 degrees Celsius.

9. The winter precipitation barrier composition of claim 8 , wherein the composition has a freezing point of less than −30 degrees Celsius.

10. The winter precipitation barrier composition of claim 1 , wherein the composition has a viscosity of greater than 0.1 cSt.

11. The winter precipitation barrier composition of claim 10 , wherein the composition has a boiling point of greater than 20 degree Celsius.

12. The winter precipitation barrier composition of claim 1 , comprising about 1 weight % to about 99.9 weight % solvent.

13. The winter precipitation barrier composition of claim 1 , wherein the composition comprises about 0.1 weight % to about 99 weight % retaining agent.
