ZINC PLATING (Acidic & Cyanide)

I. ACIDIC ZINC PLATING

“Zinc 600” represents the latest development of acid zinc chloride plating system, which offers outstanding performance in both rack and barrel operations,

it provides the following benefits:

 

ADVANTAGES

1. It consists of two components 600(C) and 600(B), therefore, it is easy to control the bath.
2. It is a low foaming bath in air agitated bath.
3. It improves deposition at elevated temperatures in both rack and barrel baths.
4. It makes the bath operates at a wide range of pH without components hydrolysis.
5. It allows the bath operation at higher current densities.
6. It minimize burning.
7. It plates directly on: carbonitrided, carburized or case-hardened steel and malleable cast iron.
8. It gives excellent ductility, thus the tendency forblistering is reduced when plating thick deposits.
9. It results in an excellent leveling which means flexible production.

 

"Acidic Zinc" system consists of the following items:

  • “Zinc 600 C”: Carrier.
  • “Zinc 600 B”: Brightener.

 

II. CYANIDE ZINC PLATING

 “Zinc 850 Y” represents the latest development of cyanide zincwhich offers outstanding performance in both rack and barrel operations,

it provides the following benefits:

 

ADVANTAGES

1. It is a liquid brightener.
2. It is suitable for rack and barrel plating.
3. It is suitable for use in medium & high cyanide baths.
4. It works at relatively high temperature.
5. It is very economical brightener, it works well at low brightener concentration.
6. It is very stable.
7. It gives very ductile zinc deposits.
8. It gives excellent corrosion resistance.
