Product Description
3-(1-Pyridinio)-1-propanesulfonate, commonly referred to as PPS, is a high-purity zwitterionic compound belonging to the sulfobetaine class. It functions as a highly effective surfactant and is primarily utilized as a key additive in the electroplating industry. Its main role is as a brightener and leveling agent in nickel plating baths, where it helps produce exceptionally bright, ductile, and uniform nickel deposits, even in high-current-density areas. Its stability and performance make it an indispensable component for decorative and functional plating applications.
