1.The KCR-25 process is a high speed chromium plating process. Its cathode efficiency may be up to 23% ~26%.
2.Higher cathode current density, 60 ASD (ampere per square decimeter) or over, can be applied; it will accept more
current before burning will take place.
3.The deposition rate of KCR-25 bath is two to three times faster than conventional chromium baths.
4.Unlike other containing fluoride baths, the KCR-25 process dose not cause cathodic low current density etching.
5.The KCR-25 process deposit has a microhardness in the 950 to 1100 KHN100 range.
6.The KCR-25 process deposit is microcracked at greater than 400 cracks per centimeter, so that its corrosion
resistance will be improved.
7.The KCR-25 process has better throwing uniformity, its deposit is bright, shine and smoother.
8.No special pretreatments, anodes and plating tanks are required; those used for conventional hard chromium plating
baths are usually sufficient for the KCR-25 process.
