Acid Salts For Zinc

Free-flowing acid salts are used to deoxidize or activate zinc in preparation for electroplating and metal finishing processes.  Therefore, acid salts for zinc are critical to the success of zinc plating and finishing.

Acid Salt 829

  • Acid Salt 829 is for use with water on copper as a replacement for mineral acids

Operating Conditions:

Operate at 4 oz. per gallon (30 g per L) at room temperature for 30 seconds.

Equipment Requirements:

Tanks:

  • Koroseal lined tank satisfactory to 150° F (66° C).
  • High temperature rubber is recommended for temperatures exceeding 150° F (66° C).
  • At room temperature, rubber, polyethylene, PVC or polypropylene are satisfactory.

Heating Coils:

  • Karbate
  • Graphite
  • Teflon

Ventilation:

  • Positive ventilation is required when the solution is heated or when current is used.
  • All ducting and blowers must be chemical resistant.

Solution Makeup:

To make the solution, fill tank 2/3 full of water and stir in dry salts until powder is dissolved. After Acid Salt 829 is
added to the solution, adjust the level and temperature to operating conditions.

Mirapic AS-839L

  • Mirapic AS-839L is a liquid version of Acid Salt 839.
  • Used for activating steel, copper, and zinc
  • Unlike conventional mineral acids, dilution with water products produces less heat
  • Normal precautions when working with mineral acids should be observed

Operating Conditions:

Operate at 25% at room temperature for 30 seconds.

Equipment Requirements:

Tanks:

  • Koroseal lined tank satisfactory to 150° F (66° C).
  • High-temperature rubber is recommended for temperatures exceeding 150° F (66° C).
  • At room temperature, rubber, polyethylene, PVC or polypropylene are satisfactory.

Heating Coils:

  • Karbate
  • Graphite
  • Teflon

Activator 34

  • Activator 34 is a dry powder containing acid salts and surface active agents
  • For use with water on all metal as a replacement for mineral acids.
  • Very effective on zinc die cast alloys, tin, lead, leaded brass, bismuth alloys, white metals, and beryllium copper

Operating Conditions:

Concentration:

  • 4 oz. per gallon. (30 g per L)

Temperature:

  • Room temperature

Time:

    • 15 seconds to 5 minutes

Equipment Requirements:

Tanks:

  • Tanks made of or lined with; Polyethylene, PVC.

Solution Makeup:

To make a solution, fill tank ⅔ full of warm water between 110 – 120° F (43 – 49° C). Slowly dissolve the total
amount of Activator 34 required for the recommended concentration. The temperature of the solution will
lower. The temperature of the solution will lower during mixing. If the temperature falls below 65° F (18° C), the
immersion time of the work will increase significantly. It may be necessary to use warm water to prevent this. It
is not recommended using a higher concentrations to prevent longer immersion times as doing this will result in
greater drag-out losses
