Copper

MAR COPPER-PRO ELITE 78

The MAR COPPER-PRO ELITE 78 is an alkaline non cyanide or pyro copper system designed to plate on a variety of base metals. This system is non-toxic, mildly alkaline copper plating solution designed to deposit a fine grained, smooth and ductile copper layer. It can also be used on zinc-based die-castings and aluminum but may require a strike solution.

Advantages

Some of the advantages of the alkaline non cyanide pyro free copper strike are as follows:

• Contains no cyanides.
• Fine grain lustrous deposit.
• Ductile smooth deposit.
• Excellent covering power.
• Good adhesion on aluminum and stainless steel.
• Can be used as a pre plate to acid copper.

Plating Solution Make Up

Make-Up With Liquid Concentrates

1. Half fill plating tank with clean water, preferably distilled or deionized.
2. Add, in order, for each 100 gallons of plating solution, stirring after each addition:
   • 30 gallons Elite 78-MU
   • 10 gallons Elite 78-C
   • 5 gallons Elite 78-B
   • 6 gallons Elite 78 Auxiliary
3. Hang clean un-bagged (oxygen free or rolled phosphorized) anodes in tank. The use of phosphorized copper anodes is preferred.
4. Add water to operating level, preferably 15 cm. (6") below tank rim, turn on agitation (air or solution recirculation) and filtration.
5. Check pH. If above 9.5, lower to 9 with Sulphuric acid and if below 8.8, raise with cautious additions of Elite 78-B.
6. Plate a rack of "dummy" panels under normal operating conditions to check solution performance.

Make-up of strike solution

• 18% Elite 78-MU
• 10 % Elite 78-C
• 5 % Elite 78- B
• 6 % Elite 78 Auxiliary
