Abstract

A composition for paint removal and methods of making and of using the composition are provided. The paint remover composition comprises a component selected from the group consisting of THF, toluene, acetone, DMSO, dioxalane, 1,2 trans dichloroethylene, and a combination thereof.

Claims (37)

1. A paint remover composition comprising:

tetrahydrofuran (THF) ranging from 4 weight % to 75 weight %,

acetone ranging from 4 weight % to 75 weight %,

ammonia and

a component comprising dye, paraffin wax, antioxidant, surfactant, thickener, fumed silica, corrosion inhibitor, peroxide inhibitor, or any combination thereof.

2. The paint remover composition according to claim 1 , wherein the composition further comprises toluene, dimethyl sulfoxide (DMSO), 1,2 trans dichloroethylene, or a combination thereof.

3. The paint remover composition according to claim 1 , wherein the THF is present in a range of 4 weight % to 50 weight % and acetone is present in a range of 4 weight % to 50 weight %.

4. The paint remover composition according to claim 1 , wherein the composition is in a form of a liquid or an aerosol.

5. A method of removing paint comprising applying the paint remover composition of claim 1 to a painted surface, and removing paint from the painted surface.

6. The paint remover composition according to claim 4 , wherein the THF is present in a range of 29.5 weight % to 49.5%, and the acetone is present in a range of 40 weight percent to 46.95%.

7. The paint remover composition according to claim 2 ,

wherein the composition further comprises DMSO, and wherein the DMSO is present at a range of 4 weight % to 90 weight %.

8. The paint remover composition according to claim 2 ,

wherein the DMSO is present at a range of 20 weight % to 75 weight %.

9. The paint remover composition according to claim 2 ,

wherein the DMSO is present at a range of 4 weight % to 45 weight %.

10. The paint remover composition according to claim 2 ,

wherein the DMSO is present at 24.75 weight %.

11. The paint remover composition according to claim 1 ,

wherein the component is present in a range of 0.01 weight % to 12.5 weight % based on the weight of the composition.

12. The paint remover composition according to claim 11 ,

wherein the component comprises paraffin wax and fumed silica.

13. The paint remover composition according to claim 12 ,

wherein the component comprises a corrosion inhibitor.

14. The paint remover composition according to claim 13 ,

wherein the component comprises an antioxidant.

15. The paint remover composition according to claim 11 ,

wherein the component comprises a corrosion inhibitor.

16. The paint remover composition according to claim 11 ,

wherein the component comprises an antioxidant.

17. The paint remover of claim 1 , wherein the paint remover includes at least two components selected from the following: a dye, paraffin wax, antioxidant, surfactant, thickener, fumed silica, corrosion inhibitor, and/or a peroxide inhibitor.

18. The paint remover of claim 1 , wherein the paint remover includes at least three components selected from following: a dye, paraffin wax, antioxidant, surfactant, thickener, fumed silica, corrosion inhibitor, and/or a peroxide inhibitor.

19. The paint remover of claim 1 , wherein the paint remover includes at least four components selected from the following: a dye, paraffin wax, antioxidant, surfactant, thickener, fumed silica, corrosion inhibitor, and/or a peroxide inhibitor.

20. The paint remover of claim 1 , wherein the paint remover includes at least five components selected from the following: a dye, paraffin wax, antioxidant, surfactant, thickener, fumed silica, corrosion inhibitor, and/or a peroxide inhibitor.

21. The paint remover of claim 1 , wherein the paint remover includes at least six components selected from the following: a dye, paraffin wax, antioxidant, surfactant, thickener, fumed silica, corrosion inhibitor, and/or a peroxide inhibitor.

22. The paint remover of claim 1 , wherein the paint remover includes at least seven components selected from the following: a dye, paraffin wax, antioxidant, surfactant, thickener, fumed silica, corrosion inhibitor, and/or a peroxide inhibitor.

23. The paint remover of claim 1 , wherein the paint remover includes a dye, paraffin wax, antioxidant, surfactant, thickener, fumed silica, corrosion inhibitor, and a peroxide inhibitor.
