Ethylene thiourea dithiopropanesulfonate sodium (SN110)

Applications

• In copper plating applications, It is utilized in acidic copper baths to refine grain structure, thereby enhancing both the leveling properties and hardness of the plated deposit.

• It is employed in both decorative and functional electroplating contexts, finding application in hardware plating, copper electroforming, printed circuit boards, and the lithium-ion battery copper foil industry.

• Specifically within the copper foil electroplating process for lithium-ion batteries, it significantly improves the tensile strength of the copper foil.
