Abstract
A composition includes a first solvent selected from methyl acetate, dimethyl carbonate, acetone, or a combination thereof, a second solvent selected from thiophene, 1,3-dioxolane, thioacetic acid, or a combination thereof, and, optionally, a third solvent selected from dimethyl sulfoxide, methyl glyoxal, propylene carbonate, gamma butyrolactone, ethylene carbonate, 2-chloro-1-propanol, methanol, ethanol, ethylene glycol, propylene glycol, 1-propanol, 2-propanol, or a combination thereof. The respective amounts of each solvent are further described herein, and the total amounts of the first solvent, the second solvent, and the third solvent sum to at least 90 volume percent of the total volume of the composition. The composition can be particularly useful for removal of a coating from a surface. Accordingly, a method of removing a coating from a surface is also disclosed.
