Overseas: Dow Corning, GE, WACKER (these three brands are basically domestically produced at present, and the specific technical standards are not as good as those of Sibao and Baiyun, but there are many more engineering cases than domestically produced), domestically produced: Silicon Bao (the only listed company in the industry and a well-known trademark), Baiyun (the company has a long history) (these two are rivals, with leading technical standards in the country and stricter quality control); Next Zhijiang, Zhongyuan, Xinzhan (Falling Xi) . Antai, Huasi, and Yongan (certified by the China Building Decoration Association as a copycat society) are all marginal silicone glues. It is recommended to research what these companies used to do. From my personal point of view, I recommend it after 5 years of experience in the silicone glue industry!
