Sodium Formaldehyde Bisulfite CAS 870-72-4

Details:

1. Sodium hydroxymethylsulfonate (PN) is a kind of polymer, which needs to be used in combination with SP, m, N, P, aess, GISs, etc. 2. It has a strong cathodic polarization effect, which can significantly enhance the brightness of the low area. When PN is used, it is found that the brightness is insufficient, which can appropriately increase the amount of high-level agent (PDS). 3. PN is the best high temperature carrier in the copper acid brightener, which is suitable for complex workpiece electroplating. 4. It can be used in the range of 15 ºC ~ 45 ºC. PN is not only suitable for cupric acid, but also for the brightener of cyanide free zinc plating. 5. Heavy metal complexing agent for nickel plating. 6. It is widely used. Sodium hydroxymethylsulfonate can effectively complex copper, zinc, lead and other metal ions. Lead zinc ore flotation agent and color photo assistant (anti pollution and fading), cotton printing industry. 7. It does not contain SO32 -, and has the functions of impurity removal, displacement and softness

it is used in the production of medicine carcinodi-m, new arsfanamine and isoniazid sulfonate sodium. Used as the intermediate of electroplating additive, used to prepare brightener for nickel plating Brightener for nickel plating can improve brightness and leveling effect
