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.
