Use: Phenolsulfonic acid (referred to as PSA) is The sulfonated product of phenol is the most important additive in the acid tin plating process and also has the effect of foaming the acidic resin. In the tinplate production line of the acidic process (such as the Fluorstein process), phenolsulfonic acid is mainly used as an additive in the tin plating solution to maintain the acidity of the tin plating solution, which is Sn2+ The production provides H+ and prevents the solution's Sn2+ dissolved oxidation into Sn4+ to keep the plating liquid It is stable and well conductive, and finally makes the tin plating layer of the tin plate produced fine, precise and uniform, with good surface finish and strong tin layer bonding force. |
