KCR-25 Chrome Plating Brightener with Fast Deposition Speed Chloride-Free Formula for High Micro-Hardness Hard Chromium Plating
KCR-25 Hard Chrome Plating Chemicals Brightener High Cathode Efficiency
1. Properties
1. With high cathode efficiency, it may be up to 23%-26%.
2. The current density even over 60A/dm2 is available.
3. The deposition speed for KCR-25 bath is 2-3 times faster than conventional hard chromium process.
4. It is chloride-free, the KCR-25 process dose not cause erosion of the workpiece in low current density area.
5. The micro-hardness of the plating is up to 950HV-1100HV100.
6. The amount of the micro cracks of the plating may be up to 400/cm, so it improves the corrosion resistance ability of the plating.
