Acid Copper Brightener For base layer of Button, Zipper, Buckle bright and shining, best choicce for copper layer for hardware
510Acid Copper Brightener for base Layer of Button, Zipper, Buckle (rack plating)
Purpose and Feature:
1. Fast speed of brightening, with clear and sheen layer, luster in the low area performs better.
2. Wide range of current density with a layer of excellent leveling.
3. The layer not easy to bring needle hole or hard spots, it is easy to control.
4. High concentration brightener; low consumption and high cost effectiveness.
5. Especially appliable for copper plating on ferrous, copper alloy, zinc alloy, and aluminous alloy.

Bath Preparation:
1. Pour water into the tank with 50% by the volume; the chloride ion containing in the water should not less than 70 mg/L. Fill in the required copper sulfate and stirring until it is completely dissolved.
2. Put in 2g/L active carbon powder and stirring for 1 hour; then leave it still for 4 hours.
3. Pour the solution into the clean electroplating tank by the filter pump then fill in water to the water level, slowly put in concentrated sulfuric acid, stirring the solution with force due to it releases great amount of heat.
4. Cool the bath to 25 °C, analyze the containing of chloride ion in the bath, if it is insufficient, please fill in adequate HCl until the chloride ion reach to the standard.
5. Fill in the additives as listed on above, stirring until even. Under the normal condition, after electrolyze the bath by 3-5 ampere hour per liter, it can start production.
It has been widely applied in rack plating, as the based layer for button, zipper, buckle, get a shining and bright layer of copper.
Stable and easy to perate make it best-seller in domestic market.
