Heavy Gold Stripper S-20 is a highly effective gold stripping agent supplied in concentrated liquid form. It is mixed with potassium cyanide solution to form a gold stripping solution. The stripping rate is fast, approximately one micron per minute, without attacking the base metals such as nickel, white bronze and stainless steel. After gold stripping, there is no need to polish the parts. In normal operation, the Heavy Gold stripper S-20 solution can dissolve 10g of metallic gold per liter. If there is a higher gold concentration in the bath, we suggest changing it due to drag-out.
