Function:
Sodium hydroxymethanesulfonate (PN for short) is a polymer, when used with SP, M, N, P, AESS, GISS and so on. It has an extremely strong cathodic polarization effect, which can Chemicalbook obviously enhance the brightness of the low area. when using PN, it is found that the brightness is not enough, the amount of high level agent (polydisulfide) can be increased appropriately. PN is the best high temperature carrier in acid copper brightener, which is suitable for complex workpiece plating.
Application:
Used in the production of medicine, neoarsenicalvanamine and sodium isoniazid sulfonate. Used as intermediate of electroplating additive, used to formulate nickel plating brightening agent Use Nickel plating brightening agent, can improve the brightness and leveling effect.
Storage:
Stored in a cool dry and ventilated place
