The passive oxide on the surface of stainless steel prevents plates from adhering. This solution deposits a thin layer of nickel over stainless steel to create an active surface that accepts most metal plates. Use with a nickel anode.

How To Use Midas Stainless Steel Activator
Applications: Stainless steel has a passive oxide on its surface to which most plating will not adhere. Midas® Stainless Steel Activator deposits a thin adherent layer of nickel onto stainless steel over which you can successfully plate most other metals.
Workpiece Preparation: Electroclean, water rinse and dip in a 20% hydrochloric acid dip (20% hydrochloric acid to 80% distilled water) for 30 seconds to one minute. Proceed immediately into the Stainless Steel Activator bath without rinsing.
Please Note: Hydrochloric (muriatic) acid is available at most hardware stores. Remember: always add acid to water--never water to acid.
Solution Preparation: Midas® Stainless Steel Activator is provided as a full-strength, ready-to-use solution.
Thoroughly clean your workpiece with electrocleaner and an acid dip before immersing it into plating solution.
Pour amount needed into Pyrex® beaker.
If undissolved salts are apparent, warm the solution and stir.
Allow to cool and use solution at room temperature.
Attach a pure nickel anode to the positive (+) lead and immerse in solution.
Turn on rectifier and operate at 3 to 5 volts.
Attach handling wire to the negative (–) lead, immerse workpiece and agitate. Watch for gassing. Gassing indicates proper performance of this solution.
Time in solution: 1 to 4 minutes or until desired coverage is achieved. Avoid excess time.
Water rinse, acid dip and water rinse again.
When plating job is completed, solution in beaker can be returned to storage bottle if it has not been contaminated.
How To Choose the Plating Solutions You Need
Not all solutions of the same color are created the same. Here's a tip on how to interpret the information on each solution to help select exactly the one that's right for your application. The precious-metal content in a solution is an important factor in choosing the right plating solution. Rio provides the pennyweight (dwt.) or gram (g) content of the metal in each of our MIDAS® solutions for you to see. For example, one MIDAS 24K yellow gold plating solution contains .39g (1/4 dwt.) of gold per 1-oz. bottle while another contains .8g (1/2 dwt.) per 1-oz. bottle, a higher concentration. Use this information when comparing solutions for the best buying decision for your particular application.
