METASU ZES-M/G/R
Zinc plating brightener for high performance alkaline bath
METASU ZES is a brightener for barrel-type alkaline bath, formulated to improve productivity, throwing power and moderate to low electropolish performance.
• Fast plating speed applicable for short interval processing.
• Excellent throwing power performance.
• Attractive luster and good compatibility with chromate.
• Does not burn easily which allows for use of high current density.
• High concentration formulation so the usage amount is reduced compared to conventional
• Handling is easier as it can be used for up to 35℃.
• Wastewater treatment is simple.
