1. Sodium hydroxymethyl sulfonate (PN for short) is a kind of polymer, which needs to be used with SP, M, N, P, AESS, GISS and so on.

2. It has a strong cathode polarization effect, can significantly enhance the brightness of the low region, using PN found insufficient brightness, can appropriately increase the amount of high agent (polydisulfide).

3.PN is the best high temperature carrier of copper acid brightener, suitable for complex workpiece plating. Chemicalbook.

4. In the range of 15℃ ~ 45℃ can be used, PN is not only suitable for copper acid, but also can be used for cyanide-free zinc brightener.

5. Heavy metal complexing agent for electroplating nickel.

6. Widely applicable, sodium hydroxymethyl sulfonate can effectively complexate copper, zinc, lead and other metal ions. Lead - zinc ore floating agent and color photo auxiliaries (anti-pollution and fading), cotton printing industry.

7. Contains no SO32-, with miscellaneous, walk, soft function.

Application:

1.It is used for the production of medical cancer -M, new arsine fanamine and isoniazid sulfonate.

2.Used as an electroplating additive intermediate for preparing nickel plating brightener.

3.Nickel plating brightener, can improve the brightness and leveling effect.
