  • Patent number: 6923873
    Abstract: This invention concerns paint stripping compositions which are particularly suitable for stripping paint off aircraft. The basic composition consists of a mixture of specific amounts of the following substances: aromatic hydrocarbons, dimethyl formamide; N-methylpyrrolidone; benzyl alcohol; alkanolamine; wax; wetting agent; and thickening agent. A modified composition may also contain dimethyl sulfoxide and a terpene solvent. The invention also includes the method of stripping paint from an aircraft by applying the new stripping composition onto the surface of the aircraft allowing the paint to soften and loosen under the action of the composition, or to penetrate under the paint coating, and then gently removing both the loosened paint and the stripping composition from the aircraft surface without damaging the surface.
