Acid Zinc Plating Brightener
Acid zinc plating brightener is formulated for use in chloride or sulfate zinc electrolyte systems, producing highly leveled, mirror-bright zinc deposits with excellent throwing power on complex geometries. The brightener system contains carrier, primary, and secondary brighteners to control grain refinement, leveling, and brightness simultaneously. Acid zinc plating is preferred over alkaline zinc for its higher speed, better brightness on steel and cast iron substrates, and simpler waste treatment.
