In the electroplating industry, the appearance of white fog streaks on the surface of the tin layer is a common and troublesome problem. This defect not only affects the aesthetics of the coating, but also may adversely affect the performance of the coating, such as reducing corrosion resistance and weldability. As a research and development engineer of tin plating brightener, I will explore in depth the causes of white fog striations after tin plating, and explain why the choice of tin plating brightener Sn-807 can effectively solve this problem.
The causes of white fog streaks after tin plating are complex and varied, which may involve the composition of plating solution, plating process parameters, surface state of substrate and so on. First, impurities and unstable components in the bath can lead to uneven deposition on the surface of the coating, resulting in the formation of white fog streaks. Secondly, factors such as uneven current density distribution, improper temperature control and insufficient stirring during electroplating may also lead to a decrease in the quality of the coating and produce white fog streaks. In addition, if the oil, oxide and other pollutants on the surface of the substrate are not completely removed, defects will also form on the surface of the coating, which is manifested as white fog stripes.
In view of these causes, the use of suitable tin plating brightener is particularly important. Sn-807, the tin plating brightener introduced by Bigely, is designed to solve the problem of tin plating layer whitening. The composition of Sn-807 can effectively inhibit the whitening of the coating and improve the brightness and uniformity of the coating. The formula can ensure the high stability of the plating solution and avoid the occurrence of side reactions such as cathode hydrogen evolution, so as to improve the adhesion and corrosion resistance of the coating.
