## Abstract

An improved composition for protecting a vehicle, building, or airplane surface that will be painted or mechanically processed. For example, certain regions of a vehicle, building, or airplane may be masked in accordance with the present disclosure to protect those regions from paint overspray. The composition produces a film which adheres well to a surface to be protected, with few or no pinholes. Additionally, the composition can absorb any oil or grease present on the surface which can eliminate the need for towels and chemical solvents that may create toxic fumes, hazardous waste, and flammable hazards. Further, the material can be removed easily from the surface after use by peeling the film layer away from the surface.

## Claims

### Claim 1

A liquid composition comprising an elastomeric copolymer and a solvent in which the elastomeric copolymer is dissolved wherein the composition is configured to dry after being applied to a surface, leaving an elastomeric copolymer film configured to be peeled away from the surface, the composition further comprising a color changing indicator configured to change color after the composition is dry.

### Claim 2 (depends on 1)

The liquid composition of claim 1 wherein the elastomeric copolymer is oleophilic.

### Claim 3 (depends on 1)

The liquid composition of claim 1 wherein the elastomeric copolymer is selected from polystyrene-polyisoprene-polystyrene, polystyrene-block-polybutadiene-block-polystyrene, polystyrene-block-poly(ethylene-ran-polybutylene)-block-polystyrene, polystyrene-block-polybutadiene-block-polystyrene, alpha-methylstyrene-vinyltoluene-copolymer, and ethylene-octene-1 copolymer.

### Claim 4 (depends on 1)

The liquid composition of claim 1 wherein the solvent is selected from mineral spirits, methylethylketone, toluene, p-xylene, tetrahydrofuran, and dimethoxymethane.

### Claim 5 (depends on 1)

The liquid composition of claim 1 wherein the composition is configured to be sprayable.

### Claim 6 (depends on 1)

A method of protecting a surface in vehicle, building, or airplane painting operations from paint overspray comprising the steps of applying the liquid composition of claim 1 to the surface to be protected, allowing the liquid composition to dry, painting the vehicle, building or airplane, the dried composition preventing the paint from contacting the surface to be protected, and peeling the dried composition from the surface.

### Claim 7

A method of absorbing an oil-based contaminant from a surface comprising the steps of applying a liquid composition to a surface having an oil-based contaminant thereon, the liquid composition comprising an elastomeric copolymer and a solvent in which the elastomeric copolymer is dissolved wherein the composition is configured to dry after being applied to a surface leaving an elastomeric copolymer film, allowing the liquid composition to dry, and peeling the dried composition from the surface.

### Claim 8

An oleophilic nonwoven comprising a liquid composition applied to a nonwoven material, the liquid composition comprising an elastomeric copolymer, a solvent in which the elastomeric copolymer is dissolved, and a color changing indicator, wherein the composition is configured to dry after being applied to a surface, leaving an elastomeric copolymer film.

### Claim 9 (depends on 8)

The nonwoven of claim 8 wherein the elastomeric copolymer is selected from polystyrene-polyisoprene-polystyrene, polystyrene-block-polybutadiene-block-polystyrene, polystyrene-block-poly(ethylene-ran-polybutylene)-block-polystyrene, polystyrene-block-polybutadiene-block-polystyrene, alpha-methylstyrene-vinyltoluene-copolymer, and ethylene-octene-1 copolymer.

### Claim 10 (depends on 8)

The nonwoven of claim 8 wherein the solvent is selected from mineral spirits, methylethylketone, toluene, p-xylene, tetrahydrofuran, and dimethoxymethane.

### Claim 11 (depends on 8)

The nonwoven of claim 8 wherein the liquid composition is applied to the nonwoven in a pattern wherein the pattern comprises at least one of a dot, line, circle, or wavy line.

### Claim 12

A method of absorbing an oil-based contaminant from a surface comprising providing an oleophilic nonwoven comprising a liquid composition applied to a nonwoven material, the liquid composition comprising an elastomeric copolymer and a solvent in which the elastomeric copolymer is dissolved, wiping the contaminated surface with the nonwoven, wherein the composition is configured to dry after being applied to the surface, leaving an elastomeric copolymer film, and wiping a second surface with the nonwoven wherein the oil-based contaminant is not transferred to the second surface from the nonwoven.
