  • Compositions and methods for coating removal
    Patent number: 5954890
    Abstract: Compositions and methods for removal of polymeric coatings from nonporous surfaces are provided. The method comprises the mixing of two stock solutions, a peroxide/acid solution and an alkaline solution, and immediate application to the surface to be stripped of coating. The applied mixture produces a controlled peroxide oxidation reaction causing the coating to become softened-to-release. A further step of washing or blowing with water, air, cornstarch, or plastic media will remove the softened-to-release coating. The two stock solutions are stable to storage and, when in use, are continuously mixed in a volume so as to control reaction rate, pH, corrosivity of the coating remover, and reaction rate with the coating.
    Type: Grant
    Filed: September 26, 1997
    Date of Patent: September 21, 1999
    Assignee: Eldorado Chemical Co., Inc.
    Inventors: Pat E. Smith, John M. Jasper, William R. Zinnecker, Joe R. Fredricksen
