This product is specifically designed for the stripping of defective nickel plating in both electroless nickel and electroplated nickel. It has a fast stripping speed and is also suitable for both mid-phosphorus and high-phosphorus systems. It is particularly useful for processing precision steel and copper alloy substrate materials without corroding the metal substrate. The surface of the workpiece is bright and shiny after stripping, and polishing may not be necessary before re-plating after removal of the film. The solution does not contain cyanide or anti-stain salt.
