Abstract
A method of electrolytically debonding a paint coating from an electrically nonconductive member wherein the paint coating is bonded to a surface of the nonconductive member. The method comprises providing an electrode blanket on the paint coating, the electrode blanket comprised of a first blanket layer in contact with the paint coating, a negative electrode layer in contact with the first blanket layer, a second blanket layer covering the negative electrode layer, a positive electrode layer in contact with the second blanket layer, and a third blanket layer covering the positive electrode layer. An aqueous-based electrolyte solution is applied to the electrode blanket. An electric current is passed from the negative electrode to the positive electrode, evolving hydrogen at the negative electrode, thus creating an alkaline condition thereby causing delamination and degrading of the paint coating on the electrically nonconductive member.
