METASU ZES-M/G/R
Zinc plating brightener system for high performance alkaline baths
METASU ZES is a brightener system for barrel-type alkaline baths, formulated to improve productivity, throwing power and brightness at mid to low current density areas.
<Characteristics>
- Short processing time made possible by fast plating speed.
- Excellent throwing power.
- Attractive luster and good compatibility with chromate.
- High current density can be used since it does not burn easily.
- Usage amount is reduced compared to conventional products due to high concentration formulation.
- Easy handling with possible usage up to 35°C.
- Wastewater treatment is simple.
