How was Guangqi lacquer discovered?

The discovery of Guangqi coating originated from a research and development work of Longsheng Co., Ltd., the predecessor of Guangqi Technology Company. The company's main business is automobile parts, but in the process of developing automobile paint, engineers unexpectedly found that this paint has excellent absorption effect on radar waves. Specifically, Guangqi lacquer can absorb radar waves in a certain speed range (about 24 km/h to 199 km), and when the speed reaches 100 km/h, the error will not exceed 1 km/h. This feature enables objects coated with varnish to achieve the function of radar stealth. Due to this discovery, Longsheng completed the asset injection into Shenzhen Guangqi Frontier Technology Co., Ltd. through non-public offering of shares, which mainly focuses on cutting-edge equipment technology. The application of varnish is not limited to the military field, but also includes civil and other fields that need stealth technology.
