Paint remover having reduced flammability
A composition comprises dimethyl carbonate (DMC) and dimethyl sulfoxide (DMSO) and has a flash point of 70° F. or greater. The composition has a total VOC content defined by the Environmental Protection Agency (EPA) of 50 weight percent (%) or less. The composition removes or strips paint in a period of time of two hours or less. The composition may further comprises one or more corrosion inhibitors.
1 . A paint remover composition comprising:
10 weight percent to 49 weight percent dimethyl carbonate (DMC),
dimethyl sulfoxide (DMSO) is present in the paint remover composition, and is included at a concentration of 24 weight percent or less in the paint remover composition,
12 weight percent to 25 weight percent xylene or xylene containing mixture of isomers and ethyl benzene, and
0.25 weight percent to 25 weight percent of a corrosion inhibitor,
wherein the composition removes paint and has a flash point between 70 degrees Fahrenheit and 110 degrees Fahrenheit,
wherein the ratio of DMC to xylene is from 1:2.5 to 4:1,
wherein the composition removes paint in a time period of two hours or less, and
wherein the corrosion inhibitor is a soap compound selected from the group consisting of ammonium 9-octadecenoate, monoethanolamine 9-octadecenoate, diglycolamine 9-octadecenoate, morpholine 9-octadecenoate, and a combination thereof.
2 . The paint remover composition according to claim 1 , further comprising water.
3 . The paint remover composition according to claim 1 , further comprising an additive selected from the group consisting of a surfactant, an ether containing compound, a dye, a thickener, a fragrance, a wax, and a combination thereof.
4 . The paint remover composition according to claim 1 , wherein the composition has a total VOC content of 50 weight percent (%) or less based on the weight of the total composition.
5 . The paint remover composition according to claim 1 , wherein the corrosion inhibitor provides corrosion resistance to an internal surface of a metal container containing the composition.
6 . The paint remover composition according to claim 1 , wherein the corrosion inhibitor provides corrosion resistance to an external surface of a metal container containing the composition.
7 . A method of using a composition for paint removal, the method comprising:
providing the composition of claim 1 , and
removing paint from a painted surface with the composition.
8 . The method of using according to claim 7 , wherein the composition further comprises water.
9 . The method of using according to claim 7 , wherein the composition further comprises an additive selected from the group consisting of a surfactant, an ether containing compound, a dye, a thickener, a fragrance, a wax, and a combination thereof.
10 . The method of using according to claim 7 , wherein the composition has a total VOC content of 50 weight percent (%) or less based on the weight of the total composition.
