Abstract
PURPOSE: To peel off a resin film inexpensively and efficiently, by conducting electrolysis by using an aq. caustic alkali soln. having a specified concentration as an electrolyte and a resin-coated metal as a cathode in peeling the resin film from the resin-coated metal.
CONSTITUTION: An aq. soln. of caustic soda or potash, or a mixed aq. soln. of caustic sada and caustic potash is prepd. and used as an electroyte, each soln. having a concn. of 1W20%. Electrolysis is conducted at an electrolysis temp. of 60W95°C by using, as a cathode, a metal coated with an epoxy resin or an acrylic resin. A resin film is peeled from the metal by the action of hydrogen gas formed. It is necessary to choose either caustic soda or caustic potash depending on the kinds of coated films. For example, when an acrylic resin-coated metal is treated, the resin film can be peeled off by using an inexpensive aq. caustic soda soln. But, when a thick film of an epoxy resin should be peeled off, it is necessary to use an aq. caustic potash soln.
