SA-7

Xuzhou Shengtang Optoelectronics Technology Co., Ltd. was established in 2006. It is a private technology enterprise specializing in the production of optical coating materials, with independent intellectual property rights. By the end of 2018, it had been authorized 15 utility model patents and 1 invention patent. The company is located at the intersection of Xinyi City, Jiangsu Province and Donghai County, Lianyungang City, adjacent to the national 4A-level scenic area Maling Mountain to the north and the seventh largest freshwater lake in China, Luoma Lake, a silicon resource producing area. The company has advanced cold processing production equipment and R&D technology. In cooperation with the School of Physics and Electronic Information Engineering of Jiangsu Normal University, it has established a graduate workstation to develop new coating materials. Main products include: various specifications of silicon dioxide, AF waterproof agent, lanthanum titanate, titanium trioxide, magnesium fluoride, and high-purity mixtures such as SA-7 and SA-9. They are widely used in the evaporation of anti-reflection films, multilayer films, reflective films and other film systems. Products are exported to Japan, South Korea, Germany, Taiwan and other countries and regions. At present, the company is striving to transform from a production-oriented to a research-and-development-oriented enterprise. It has established a doctoral workstation and has a technical development team composed of doctoral researchers, senior engineers and technicians, controlling trace elements, base content and impurity content in raw materials according to the needs of different customers.
