BROWN - F
Brown– F is a concentrate, rapid acting, and chemical solution to develop a brown antique finish on steel and ferrous metal surfaces at room temperature. The product is a mildly acidic solution containing no Chromates, Sulfides, Cyanides, Caustics or Phenols.
Parts must be free of grease, alkalinity or acid when Brown - F is applied. Parts must be thoroughly cleaned and deoxidized prior to blackening. Cleaner 104 is recommended for removing heavy oils and oxidation. Do not use petroleum degreasing solvents that leave a residue on the surface. Rinse thoroughly with over flowing cold water to remove residual cleaners and dust. It is important that alkaline cleaners are completely rinsed off prior to blackening.
IMPORTANT: Triple- S does NOT recommend using any sort of alcohol, solvent, acid or degreaser to clean parts prior to solution application. Cleaner 104 is a great cleaner to ready parts for Brown - F or even a powdered cleaner like Ajax or Comet are recommended. Use with a scotch brite pad and medium scrubbing to prepare the part then thoroughly rinse with fresh water.
Brown - F concentrate should be used AS IS...no dilution necessary.. A uniform brown finish will develop in a period of 10 to 60 seconds. The immersion time can be shortened or lengthened depending on the dilution rate of the solution.
Brown-F should be used as is (no dilution). Use an acid resistant container as the immersion tank. Plastic, plastic lined, glass, or rubber lined is suitable. Do not use an uncoated metal container. Determined by tests, a period of 10 to 60 seconds is needed to develop a uniform brown finish. The immersion time can be shortened by using a stronger solution or lengthened by using a weaker solution. For good results, parts must be free of oil and rust.
Clean the surface with Cleaner 104. Rinse thoroughly with cold water. Apply Brown- F solution with brush, dip 5-10 seconds and let it react the desired finish will develop, over the next few hours as the piece continues to dry. Rinse thoroughly with over flowing cold water to stop chemical reaction. To further stop the reaction, neutralizing is recommended (please refer to data sheet). Dry the piece immediately. Leaving water on the piece can cause rusting. It is recommended to protect the finish with a clear lacquer (e.g., WSL- 55 or AL-70).
