Our company was established in May 1999, primarily engaged in the development and production of fine chemical products, as well as equipment installation and technical services in the fine chemical industry. Our main products include inorganic tin series, organic protective films for circuit boards (replacing benzimidazole compounds), polyurethane anti-corrosion coatings and insulation materials specifically for chemical pipelines and containers. Anhydrous tin tetrachloride is one of our inorganic tin series products, with an annual production capacity of 2,000 tons. Utilizing dry film filtration micro-evaporation technology, our technical level ranks among the top in the industry. Since commencing production of anhydrous tin tetrachloride in 2000, our company has not experienced any safety incidents. The production process generates no waste (three wastes), thus having no impact on environmental safety.

Our company currently employs 51 people, including 27 production staff and 8 engineering technicians. All engineering technicians work on the front lines of production, and process operations strictly adhere to safety procedures, ensuring the safety of the production process.
