The methanesulfonic acid tin plating system has numerous technical advantages such as a non-toxic and stable plating solution, complete biodegradability under natural conditions, simple wastewater treatment, high current efficiency, strong throwing power, wide current density range, and low tin sludge generation. Therefore, the methanesulfonate tin plating system is the most widely used high-speed tin plating method in industry.
Tinplate, also known as tin-coated steel, is a low-carbon steel sheet with a tin coating on its surface. It combines the advantages of steel and tin, possessing the strength and formability of steel as well as the corrosion resistance and solderability of tin. High-speed coil-to-coil tin plating on steel surfaces can provide corrosion protection. Additionally, because tin ions and their compounds are harmless to the human body, and the tin coating has good corrosion resistance, ductility, and weldability, tinplate is also widely used in the processing, packaging, storage, and transportation of food, such as in canned goods.
The core of the methanesulfonic acid tin plating system lies in the additives within the tin plating solution. This area is currently monopolized by foreign companies, with limited domestic research. Therefore, developing methanesulfonic acid tin plating system additives with independent intellectual property rights is a very significant undertaking.
