Plating-grade 3-Pyridinium Propanesulfonate (PPS, CAS 15471-17-7), min. 98%, supplied wholesale by Zyntex. Zwitterionic brightener and leveler for bright nickel electroplating baths. CoA and SDS with every lot.
3-Pyridinium propanesulfonate (1-(3-sulfopropyl)pyridinium hydroxide inner salt, C8H11NO3S) is a white to off-white crystalline powder that dissolves easily in water. Its molecule carries both a positive pyridinium charge and a negative sulfonate group.
In addition, in bright nickel plating, it acts as a secondary brightener and leveler. Small amounts in Watts baths based on Nickel Sulfate, Nickel(II) chloride 6-hydrate and Boric Acid give bright, level deposits with good ductility, and it works well together with saccharin-type primary brighteners. It also appears in other electroplating processes and as an intermediate for specialty chemicals.
Plating chemical formulators value it because it produces few harmful breakdown products in the bath. For other nickel plating chemicals in our range, see Nickel sulfamate.
Typical uses include, for example:
⚡ Bright Nickel Plating
Secondary brightener as well as leveler in Watts baths.
🔩 Decorative Finishes
Additive for bright decorative nickel layers.
