Industrial Etchants for Zinc Alloys

Highly acidic etchants are used for oxide removal and etching zinc in preparation for plating and metal finishing processes.  Therefore, etchants for zinc are crucial to zinc plating and finishing applications.

Our solutions are available in the following packaging sizes:

  • 5-gallon pails
  • 55-gallon drums
  • 300-gallon totes

  • 3.5 oz. per gal. (26 g per L).

Nitric Acid:

  • (42° Be) 4.5% by volume.

Time:

  • 15 – 60 seconds

Temperature:

  • 85 – 115° F (29 – 46° C).

Equipment:

  • Mild steel lined with PVC, polypropylene. Teflon heat exchangers.

Acid Number Range:

    • 20 – 50

Solution Makeup:

Warning: Use extreme caution when adding acidic components to Mirapic ME-811. Always add acid to
water.
1. Fill tank ⅔ full with water.
2. Carefully add required amount of Mirapic ME-811 to avoid splashing.
3. Carefully add required amount of nitric acid (42° Be) over entire surface of bath to avoid splashing
and excess heat generation.
