BLACK - N
Black- N is a rapid acting chemical formula to develop a black antique finish on Nickel surfaces at room temperature. The product is a mildly acidic solution containing no chromates, sulfides, cyanides, caustic or phenols.
Clean the part with Cleaner 104. Rinse with over flowing cold water. Immerse the parts in Black- N solution for 10-60 seconds. Agitate the parts to break air bubbles and to assure solution contact with all surfaces. Plastic or plastic baskets should be used for small parts. Rinse thoroughly with over flowing cold water, then wipe dry and seal. It is recommended to protect the finish with a clear lacquer (e.g. WSL- 55 or AL-70).
