BD - 264
For Copper and Brass		  

Description:

Triple-s BD-264 is a non-fuming bright dip solution for copper, Brass or other copper alloys. Parts treated with BD-264 will have very bright surfaces which are clean and free from oxide films. In addition, a chromate film is deposited which provides good corrosion protection as well as providing a base for the bonding of paint.

FEATURES: BENEFITS:
BD-264 is a single bright dip compound. No highly corrosive liquid acid to handle reduces the possibility of accidents.
BD-264 solution is non-fuming: Lowers costs by eliminating the need for ventilation equipment. Improves working condition. Lowers maintenance costs by eliminating corrosive fumes from the atmosphere.

Operating Conditions:

Concentration: Use as is.
Temperature: 60º to 90º F.
Time: 10 second to 1 minute.

Operating Instructions:

The correct operating condition for BD-264 solution is determined by the thickness of the oxide film to be removed and by the time available for treatment. Increases in concentration will increase the effectiveness of the solution and reduce the time required. If the concentration remains constant, the time required for complete oxide removal is in direct proportion tot he thickness of the oxide coating. Parts should not be Immersed longer than in necessary to achieve satisfactory results.

Equipment:

P.V.C. Koroseal, Stainless Steel, or Polyethylene tanks are satisfactory for holding the BD-264 solution. Ventilation equipment is not required.

Control:

The best method for control is by visual inspection of work being processed. When the time required for complete oxide removal increases to the point of inconvenience, additions of BD-264 should be made to restore the effectiveness of the bath. When addition eventually fails to reactivate the bath, it should be discarded and a new BD-264 bath should be prepared.

Caution:

BD-264 contains chromic acid. When handling the solution, protective clothing and gloves should be worn. Avoid contact with combustible materials or organic compounds.

Important Notes:

When using BD-264 prior to nickel plating or antiquing, it is necessary to remove the chromate film from the surface. This may be accomplished by dipping in a 10% by volume solution of sulfuric acid or 5% caustic soda. The cycle employed should be as following:

  • Dip in BD-264.
  • Water Rinse.
  • Acid or caustic dip.
  • Water rinse.
  • Nickel plate or Antiquing.
