Description
Sulfuric acid chromium removal additive
VOP-TREAT357 is fast and gentleDechrome process,It is especially suitable for deplating the chromium layer of printing intaglio.
Advantage of：
- It is a sulfuric acid type catalyst and does not contain chloride
- Little damage to the substrate
- The deplating catalyst can produce passivation on the surface of the copper layer, therefore, it is necessary to protect the surface of the copper layer during the deplating process.This kind of protection makes it easy to obtain a good electroplating effect during the second chrome plating of the plate roller.
- Compared with the hydrochloric acid type deplating process, the toxic gas is significantly reduced
