Application and Advantage
1. Suitable for rack or barrel zinc plating.
2. Full bright and brilliant, ductile zinc deposits with good leveling.
3. Be able to work in wide temperature range because of high cloud point of the bath.
4. Be able to work in wide temperature range up to 60℃.
5. Excellent throwing power and covering power.
6. The process can be worked in wide current range and easy to control due to no burning deposit.
7. Very easy conversion from most of the acid zinc plating system by direct addition.
