PFIZER SODIUM CITRATE as your sequestering and buffering agent Complex-shaped interiors, found in many valves and pipes, frequently are beyond the throwing power of an electroplating bath. Such equipment can be successfully plated without electricity by electroless nickel plating using Pfizer Sodium Citrate. This ideal buffering agent produces brighter plate in the alkaline bath and as a sequesterant prevents wasteful precipitation of basic nickel salts. Other Pfizer chemicals of interest to metal finishers include : citric, tartaric, gluconic and oxalic acids, and their salts. Get the full details on how they help you do a superior job of cleaning, polishing and plating. CHAS. PFIZER & CO., IMC, C h e m i c a l Sales Division, 630 Flushing Ave., Brooklyn 6, Ν . Υ.
