What is Dimethyltin dichloride used for?
The core applications of dimethyltin dichloride (CAS No. 753-73-1) are mainly concentrated in material protection, plastic processing and special materials fields, which can be specifically classified into three major categories.
In the field of metal protection: “Putting on protective clothing” for magnesium alloys to facilitate the development of the lightweight industry
In fields with extremely high requirements for material lightweighting, such as aerospace and automotive manufacturing, magnesium alloys are widely favored due to their advantages of light weight and high strength. However, the corrosion-prone property of magnesium alloys has become a “bottleneck” restricting their large-scale application. At this point, the emergence of DMCT provided an effective solution to this difficult problem.
According to industry data, the domestic demand for DMCT used in magnesium alloy corrosion protection will reach 6,000 tons in 2024, representing a year-on-year growth of 12%. With the continuous increase in the demand for lightweight materials in industries such as new energy vehicles and unmanned aerial vehicles, it is expected that the demand growth rate of DMCT in this field will remain above 10% in the next two years, providing strong support for the large-scale application of the magnesium alloy industry.
Plastic processing industry: PVC stabilizers are the “core force”, ensuring product quality and safety
Polyvinyl chloride (PVC), as one of the general-purpose plastics with the largest global output, dimethyl tin Dichloride is widely used in fields such as pipes, profiles, and films. However, during the processing and use of PVC, it is prone to degradation due to factors such as high temperature and light exposure, resulting in discoloration, hardening and performance decline of the products. dimethyltin dichloride DMTC, as the core intermediate of PVC heat stabilizers, can effectively inhibit the degradation reaction of PVC and become the “core force” to ensure the quality and safety of PVC products.
High-end material manufacturing: Empowered by precursor materials, facilitating innovation in the electronics and new energy industries
In addition to traditional application fields, the application of dimethyltin dichloride DMCT in high-end material manufacturing is gradually emerging, especially in the electronics and new energy industries, where its value as a precursor material is constantly being explored.
In the field of electronic display, transparent conductive tin oxide films are key components of products such as liquid crystal displays and touch screens. After being processed by specific techniques, dimethyltin dichloride DMCT can be used as a high-quality precursor material for preparing transparent conductive tin oxide films. Compared with traditional precursors, the films prepared from DMCT as raw material have higher electrical conductivity and light transmittance, which can effectively improve the picture quality and touch sensitivity of display products. At present, this technology has been applied on a large scale in many well-known domestic display enterprises, promoting the domestic display industry to develop towards higher quality.
In the field of new energy, dimethyl tin dichloride also shows good application potential. Some research institutions have indicated that DMCT-derived organotin compounds can be used in the preparation of electrode materials for solar cells, which is expected to enhance the photoelectric conversion efficiency of solar cells. At present, the relevant technology has entered the pilot production stage. If it is applied industrially in the future, it will inject new impetus into the development of the new energy industry.
Industry experts point out that with the continuous advancement of technology and the rapid development of related industries, the application fields of DMCT will be further expanded. However, at the same time, attention should also be paid to environmental protection issues during its production and use. Through technological innovation, the DMCT industry should be promoted to develop in a green and sustainable direction, so as to better empower the development of various industries.
