AS 7059 Sn, when used with Sodium Hydroxide, is a product designed to remove Tin, Lead, Solder, Zinc and Cadmium coatings without electricity from Copper, Yellow, Nickel, Silver, Iron-Steel and Stainless. Materials can be removed from the basket without damaging the substrate and without using current. A brush is usually sufficient to smooth the polish after removal. In some cases, it may not be necessary. The oxide layer that will form on the part after disassembly is removed with 30 gr/lt Sodium Cyanide solution.
