Abstract

An emulsion-based latex aerosol paint comprises 5-50 weight percent of one or more hydrocarbon solvents, 0.05-10 weight percent of a surfactants with a Hydrophilic-Lipophilic Balance value of 4-10, 10-70 weight percent of a water-based coating emulsified into a mixture of the one or more solvents and the one or more surfactants. The emulsion-based latex aerosol paint may be additionally charged with a hydrocarbon propellant at a level of 5 to 50 weight percent. The hydrocarbon propellant may be selected from propane, butane, isobutene and mixtures thereof. A method of making an emulsion-based latex aerosol paint comprises providing one or more aliphatic solvents, adding one or more surfactants to the one or more aliphatic solvents to provide a solvent/surfactant mixture, adding a water-based coating to the solvent/surfactant mixture and emulsifying the water based coating in the solvent surfactant mixture to provide a water-based coating emulsion, and placing the water-based coating emulsion in a delivery system utilizing a hydrocarbon propellant.

First claim

What is claimed is:

1. An emulsion-based latex aerosol paint comprising:
25 percent to 45 percent by weight of a water-based coating emulsion;
5 percent to 20 percent by weight of water;
30 percent to 45 percent by weight of one or more hydrocarbon solvents;
0.05 percent to 10 percent by weight of one or more surfactants with a Hydrophilic-Lipophilic Balance value of 4-10; and
10 percent to 20 percent by weight of a hydrocarbon propellant.

2. The emulsion-based latex aerosol paint of claim 1 , comprising 15 percent by weight of the hydrocarbon propellant.

3. The emulsion-based latex aerosol paint of claim 2 , wherein the hydrocarbon propellant is selected from the group consisting of propane, butane, isobutene and mixtures thereof.

4. The emulsion-based latex aerosol paint of claim 2 , wherein the one or more hydrocarbon solvents are selected from the group consisting of one or more aliphatic hydrocarbons, one or more aromatic hydrocarbons, and mixtures thereof.

5. The emulsion-based latex aerosol paint of claim 4 , wherein the one or more aliphatic hydrocarbons comprise C-5 to C-20 alkanes.

6. The emulsion-based latex aerosol paint of claim 2 , wherein the one or more hydrocarbon solvents are selected from the group consisting of VM & P Naphtha, mineral spirits, n-hexane, and mixtures thereof.

7. The emulsion-based latex aerosol paint of claim 6 , comprising:
35 percent by weight of the water-based coating emulsion;
14 percent by weight of the water;
35 percent by weight of the one or more hydrocarbon solvents selected from the group consisting of VM & P Naphtha, mineral spirits, n-hexane, and mixtures thereof;
1 percent by weight of the one or more surfactants with a Hydrophilic-Lipophilic Balance value of 4-10; and

wherein the water-based coating emulsion comprises latex paint.

8. The emulsion-based latex aerosol paint of claim 7 , wherein the emulsion-based latex aerosol paint comprises 10 weight percent mineral spirits, 20 weight percent VM & P Naphtha and 5 weight percent n-hexane, to provide said 35 percent by weight of the one or more hydrocarbon solvents.

9. The emulsion-based latex aerosol paint of claim 1 , comprising:
35 percent by weight of the water-based coating emulsion;
14 percent by weight of the water;
35 percent by weight of the one or more hydrocarbon solvents;
1 percent by weight of the one or more surfactants with a Hydrophilic-Lipophilic Balance value of 4-10; and
15 percent by weight of the hydrocarbon propellant

wherein the water-based coating emulsion comprises latex paint.
