MAR NICKEL PRO 300 BBL

MAR NICKEL PRO 300 BBL Bright Nickel Process is a single brightener system for nickel plating of both ferrous and non-ferrous metals and plastic substrates specially formulated for barrel plating. The process produces uniformly bright deposits with exceptional leveling, ductility, and receptivity to chromium plate.

MAR NICKEL PRO 300 BBL Bright Nickel Process is normally maintained with one addition agent and operates effectively over a wide solution composition range. This process is ideal for all high volume production applications where simplicity of operation and control is required.

• The system is maintained with one addition agent, thus allowing a simple operation and control.
• Exceptional leveling and ductility which give a high quality finish.
• Superior receptivity to chromium for better chromium coverage resulting in a higher quality finish.
• Operates effectively over a wide solution composition range, which the process ease of operation.

EQUIPMENT

PLATING TANKS

Tanks should be lined with PVC, polypropylene, polyethylene, rubber, or Koroseal. Fiberglass and stress-relieved welded polypropylene tanks can be substituted if necessary. Tanks molded of polyethylene or polypropylene should not be used because of mold release contamination.

Before initial use, the tanks should be leached for 24 hours with a solution of 5% Sulfuric Acid. Drain the tanks and rinse thoroughly before solution makeup.

COOLING COILS

The bath generates heat during operation and should be cooled to produce consistently good results. Heat exchangers fabricated from Teflon coated titanium, Karbate, TFE, or other fluorocarbon materials are satisfactory.

BUS BARS

Anode and cathode bars should be protected from solution contact as much as possible to avoid corrosion and plating solution contamination. Chemically resis¬tant tape or plastic coatings are suggested.

FILTRATION

Filtration is highly recommended for both rack and barrel. A coarse polypropylene cartridge (about 10 micron) with a polypropylene core is also highly re¬commended. Filter cartridges must be leached in hot water to remove organic materials prior to use. A turnover rate of 1 – 3 times the solution volume per hour is suggested. Activated carbon, with a precoat of filter aid should be added at 1 to 3 pounds per 1,000 USG of solution per week. When the flow rate drops significantly, at which time, the filter should be cleaned and repacked. Leaf type of filter suitable for nickel solutions can be used.

BARRELS

Barrels must be PVC or high density PVC.

AGITATION

Agitation is accomplished by the use of the filtration unit and by the rotation of the barrels.
