Abstract
A composition includes methyl acetate, dimethyl carbonate, acetone, or a combination thereof, dimethyl sulfoxide, methyl glyoxal, propylene carbonate, gamma butyrolactone, ethylene carbonate, 2-chloro-1-propanol, or a combination thereof, and optionally thiophene, 1,3-dioxolane, thioacetic acid, or a combination thereof. The respective amounts of each solvent are further described herein, and the total amounts of methyl acetate, dimethyl carbonate, acetone, dimethyl sulfoxide, methyl glyoxal, propylene carbonate, thiophene, 1,3-dioxolane, and thioacetic acid 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.
