Recently, the National Intellectual Property Administration of China has granted a patent entitled A Light-Moisture Dual-Curable Silicone Resin as well as Its Synthesis Method and Application. Publication No.: CN122427380A Application No.: CN202610903590.1 Publication Date: July 21, 2026 Filing Date: June 23, 2026 Inventors: Li Wanli, Wang Qingfu, Pan Sineng, Zhao Yi, Liu Ji, Zhang Puzhuo Patent Agency: Hangzhou Shantai Patent Agency (General Partnership) Patent Attorney: Duan Song IPC Classification: C08G77/38, C09J183/07, C09D183/07
According to the patent abstract, the invention falls within the technical field of silicone resin synthesis and relates to a light-moisture dual-curable silicone resin as well as its synthesis method and application. The resin backbone features an alternating structure composed of hydroxyl silicone oil and dialkoxysilane coupling agents containing photocurable groups, with both terminals capped by end-capping agents. Functional groups, crosslink density and material properties can be flexibly regulated by adjusting the molecular weight of hydroxyl silicone oil, molar ratios of raw materials and types of end-capping agents.
The synthesis process includes vacuum dehydration, polymerization and end-capping reactions under nitrogen atmosphere. Titanate, organozinc or organotin is adopted as the catalyst, and antioxidants are added to enhance stability. Low-boiling substances are removed in post-treatment to obtain the final product.
Combining the merits of rapid photocuring and shadow-free moisture curing, the resin boasts uniformly distributed photocurable groups. The hardness, flexibility and adhesion of cured coatings are tunable. It addresses the drawbacks of existing products such as uneven group distribution, single mode for crosslink density adjustment and poor adaptability. The process features mild reaction conditions, low costs and favorable prospects for industrialization.
The company’s core businesses cover two major sectors: agrochemicals and silicon-based new materials. It also develops three strategic segments including optical fiber & cable, biopesticides and glyphosate. In 2025, the company achieved operating revenue of RMB 14.625 billion, ranking 3rd among 32 comparable peers. Its revenue figure far exceeded the industry average of RMB 4.954 billion and the industry median of RMB 2.728 billion.
