Q. I've been told that sodium allyl sulfonate (SAS) and sodium vinyl sulfonate (SVS)are used as brightening agents for nickel electroplating. Is this the case? If so, 1) is it only for nickel electroplating, and 2)are the chemicals purchased by electroplaters or by brightener suppliers? I ask this because a supplier of these materials for other applications is interested in expanding into the electroplating market.Sam K [last name deleted for privacy by Editor]

A. Sulphonates are used in the metal finishing industry as surfactants and I know some of them can impart a brightening effect on nickel plating. It is difficult to say which sulphonates are used as the major supply houses do not generally give too much information about their systems.

A. Sulfonates are used as brighteners in Nickel plating. Sodium alyl sulfonates, Saccharine, and several others. I suggest you contact suppliers who manufacture nickel brighteners to offer your products. Platers almost universally buy proprietary brighteners systems from plating suppliers.
