METHOD FOR REMOVING RESIDUAL PRECIOUS METAL CATALYST FROM THE SURFACE OF METAL PLATED-PLASTICS

摘要

METHOD FOR REMOVING RESIDUAL PRECIOUS METAL CATALYST FROM THE SURFACE OF METAL-PLATED PLASTICS A method for removing residual precious metal catalyst from a plastic, metal-plated surface is disclosed. The method involves the oxidation of the precious metal without degrading the plated metal or the plastic, followed by washing away the oxidized precious metal. This invention further includes methods for the plating of metal directly on the surface of a plastic substrate.
