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.
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 (+) lead, immerse workpiece and agitate.
- 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 if it has not been contaminated.
