In the automotive industry, plating on plastics is mainly used in interior and exterior trims, as well as electronic components. Plating on plastics not only enhances the fashionable appearance of cars but also gives the overall vehicle a sense of high-end quality. Furthermore, Plating on plastics is not only easy to mold and control in size, allowing for the creation of relatively complex and diverse shaped parts, but its surface can also exhibit various high-grade metallic textures.

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.

General electroplating technology refers to the commonly used electroplating engineering techniques in industries such as hardware and sanitary ware. It is a process that utilizes electrolysis to deposit a layer of metal or alloy onto the surface of metal or other material workpieces, thereby preventing metal oxidation and improving wear resistance, conductivity, reflectivity, corrosion resistance, and aesthetics. General electroplating processes typically involve the use of specialized chemicals such as pretreatment chemicals and electroplating additives.

The surface treatment process for hardware and sanitary ware products generally involves steps such as pretreatment, alkaline copper plating, acid copper plating, nickel plating, and chromium plating. Each step requires the use of general electroplating chemicals. Therefore, there is a huge demand for related general electroplating chemicals in the surface treatment process of hardware and sanitary ware products.
