MAR EN PRO ENDEP BLACK is an alkaline electroless NICKEL ALLOY system producing a decorative smoky black finish suited for the fixture and automotive industries.
MAR EN PRO ENDEP BLACK is an alkaline electroless nickel process formulated to deposit a BRIGHT SMOKY FINISH onto steel and zincated aluminum or its alloys.
MAR EN PRO ENDEP BLACK is capable of deposition of rates 0.2 mils per hour without sacrificing bath stability.
MAR EN PRO ENDEP BLACK is supplied as a three-component liquid system. MAR EN PRO ENDEP BLACK A and MAR EN PRO ENDEP BLACK B is only used for bath make-up. The bath concentration is maintained with MAR EN PRO ENDEP BLACK A and MAR EN PRO ENDEP BLACK C.
A new MAR EN PRO ENDEP BLACK solution requires 6% by volume of MAR EN PRO ENDEP BLACK A and 18 % by volume of MAR EN PRO ENDEP BLACK B and the remainder deionized water. Make up working solutions as follows:

MAR-Tech Holdings Inc. gives no warranty, expressed or implied and the products are sold upon condition that the purchasers will make their own tests to determine the quality and suitability of the product.

Optimum bath loading is 0.2 to 0.8 ft2/gallon.
Avoid prolonged periods at working temperature without a reasonable load in the solution. Long idle periods at high temperature can cause solution imbalance and plate-out, while wasting heat and expensive chemicals.
The plating rate of the MAR EN PRO ENDEP BLACK bath and the phosphorus content of the deposit it produces is primarily a function of operating temperature, pH, reducer content and age of the solution. Generally, optimum phosphorus levels are obtained at slower plating rates (e.g., 0.3 mils per hr.)
As operating temperature, pH, and/or reducer content increases, plating rate increases, and the phosphorus content of the deposit decreases. As the solution ages, plating rate decreases and phosphorus content will increases. Increasing pH and /or operating temperature can offset this decrease in plating rate.
Solution replenishment should be made based on regular analysis for nickel.
