ACTANE 341 Liquid concentrate

Transcription

1 Liquid concentrate ACTANE 341 is a liquid concentrate when dissolved in water produces an acid solution designed to replace most mineral acid pickling and activating solutions used in electroplating, phosphating, and heat treating applications. This unwetted activator will produce a smut-free, active metal surfaces on steel, zinc, brass, copper, nickel, aluminum, pewter, Kovar and Invar. READ ENTIRE TECHNICAL DATA SHEET BEFORE USING THIS PRODUCT. When used as a cathodic electrolyte, the ACTANE 341 acid activator is effective in removing tenacious oxides, smuts and scale. The use of cathodic current will improve the effectiveness of nickel activation cycles.

3 Page 3 of 5 OPERATION High concentrations of ACTANE 341 acid activator may etch some base metals and low acid concentrations may result in subsequent plating problems. The ACTANE 341 acid activator process should be operated and maintained at recommended concentration levels. Routine acid analysis should be used to determine maintenance additions. If problems persist following solution adjustments, the solution should be discarded and replaced. (A common practice is to discard the acid activator solution concurrently with the discarded alkaline cleaner.) EQUIPMENT NEEDED Tanks Heating Coils Ventilation Electrodes (when current is used) Lined tanks required. Koroseal linings are recommended for temperatures up to 150 F (66 C). For temperatures in excess of 150 F (66 C), high temperature rubber is recommended. For ambient temperatures; rubber, PVC, polyethylene, polypropylene or lead may also be used. Karbate, Graphite or chemical lead. Required for heated solutions and/or when using current. Solution is classified A-3 by OSHA. Graphite or chemical lead. CONTROL The following analytical procedures are recommended for use by personnel who have been trained to use laboratory practices which are considered safe and prudent by chemical industry standards. Such practices include suitable personal protective equipment, the use of proper equipment, the use of proper methods of handling all chemicals and proper laboratory procedures. Use only analytical reagent grade chemicals and deionized or distilled water in the following analytical procedures. CAUTION: The following procedures involve the use of potentially hazardous chemicals. Consult manufacturer's material safety data sheets and follow the appropriate safety precautions. Equipment Needed 10.0 ml pipet 25 ml graduated cylinder 50 ml buret 300 ml Erlenmeyer flask Reagents Needed Procedure 1.0 N Sodium Hydroxide Standard Bromcresol Green Indicator ANALYSIS OF ACTANE Pipet 10 ml of the ACTANE 341 acid activator to be analyzed into a 300 ml Erlenmeyer flask. 2. Add approximately 25 ml distilled water. Swirl to mix. 3. Add 3 drops of Bromcresol Green Indicator. 4. Titrate the solution in the Erlenmeyer flask with a standardized 1.0 normal sodium hydroxide solution to a blue-green end point.

SAFETY AND HANDLING INSTRUCTIONS DANGER! ACTANE 341 AND THE OPERATING SOLUTION CONTAIN AMMONIUM BIFLUORIDE AND SULFURIC ACID, WHICH MAY CAUSE SEVERE SKIN AND EYE BURNS. ENSURE THAT COMPANY PROCEDURES AND EQUIPMENT FOR FIRST AID AND MEDICAL TREATMENT IN CASE OF FLUORIDE EXPOSURE IS IN PLACE HAZARDS: ACTANE 341 and the operating solution contain ammonium bifluoride and sulfuric acid which may cause severe burns to skin and eyes, possible blindness. Inhalation of vapors or mist may cause burns to respiratory tract, headaches, pulmonary and edema. Ingestion may cause severe burns of mouth, throat, esophagus and stomach, maybe fatal. Contact with most metals will generate hydrogen, a highly flammable and explosive gas. May react violently with water. Sulfuric acid is a potential carcinogen. ACTANE 341 and the operating solution also contain ammonium bifluoride, which may be fatal if swallowed or inhaled. Chronic exposure to fluoride may cause mottling of teeth and bone damage (osteosclerosis) and fluorosis. Do not get in eyes, on skin, or on clothing. Do not inhale or take internally. FIRST AID: In case of contact of ACTANE 341 or the operating solution with skin or eyes, flush with plenty of clean, cool water for 15 minutes; for eyes get immediate medical attention. Remove contaminated clothing and shoes. Treat for fluoride exposure if necessary, according to your company procedures. HANDLING INFORMATION: When preparing or adding to solutions, always add ACTANE 341 slowly and cautiously. Do not get in eyes, on skin, or on clothing. Avoid breathing vapors or mist. Do not take internally. When handling ACTANE 341 or the operating solution, wear protective clothing, chemical safety goggles, respirator, face shield and rubber gloves. Avoid contact with alkalis, reducing agents, combustibles or any other foreign material. Exhaust ventilation is required to remove vapors or mist that may be generated during make-up and operation. Wash thoroughly after handling. CONTAINER INFORMATION: Keep containers tightly closed. Store indoors in a cool, dry, well-ventilated area. Keep out of sun and away from alkalis and combustibles. Loosen closure cautiously when opening. Do not reuse containers, wash before disposal. Improper disposal or reuse of container may be dangerous and illegal.
