 CASWELL REPROCHROME® PLATING INSTRUCTIONS

Caswell REPROCHROME® is a unique Cobalt/Tungsten plating solution that provides a bright,
chrome-like plate onto copper, brass, nickel, steel and most other ferrous and non-ferrous metals.
For best corrosion resistance and shine, we recommend plating in copper, then nickel before
REPROCHROME® plating.

REPROCHROME® comes pre-mixed and ready for use. Just add REPROCHROME® brightener
at the rate of 3ml per 1000ml (0.40 fl oz per 1 Gal) of REPROCHROME® Starter (but don’t add it
yet)

Operating Instructions:

    1. Use HDPE or PVC plastic tank. Clean and rinse thoroughly with DISTILLED WATER
        before use.
    2. Install stainless steel anodes and maintain at least a 1:1 ratio of anode surface area to
        part surface area.
    3. Install pump agitation to keep solution moving.
    4. Pour REPROCHROME® starter into tank to required level.
    5. Heat bath to 140 deg F with a stainless steel or titanium heater plus thermostat.
    6. Plate a cleaned dummy part (scrap metal as big as you can find that will fit in the tank) at
        5V DC for 5-15 mins.
    7. Remove dummy and add REPROCHROME® brightener at the rate of 3ml per 1000ml
        (0.40 fl oz per 1 Gal) – no point using your brightener on the dummy part.
    8. Install part to be plated.
    9. Plate at 0.07 amps per square inch of part surface area at approx 5 volts.
    10. Plate for 1-2 minutes

Some shadowing and discoloration is normal in a brand new bath. Plate dummy parts until an
even color is achieved. This might also occur if bath is not used for periods of time.

Solution pH is 9.9-10.2. Read pH at 140F with pump agitation.

Troubleshooting:

Problem                                            Solution
No plating in low areas or patchy plating          Add REPROCHROME® Starter to replenish.
                                                   Increase current.

Light Deposit                                      Increase temperature and/or current
Milky Solution with plating defects                pH out of range or replenisher additions too
                                                   large. Add water or replace solution.


Theoretical bath life is 50 sq ft per 1 gallon of REPROCHROME® bath.
