Organosilicone resin is a semi-inorganic cross-linked polymer with Si-O-Si main chain and organic groups connected to silicon atoms. It is made of polyfunctional organosilane by hydrolysis and condensation, and can be further transformed into an insoluble and insoluble thermosetting resin with three-dimensional structure under heating or in the presence of catalysts. Although the market share of silicone resin is small compared with silicone compounds such as silicone oil, silicone rubber, silane coupling agent, it has an irreplaceable position in many fields, such as being used as H-class motor coil impregnating paint, high temperature insulation paint, high temperature adhesive, and mica plate, tape drying agent.

Silicone resin manufacturing process mainly includes the following steps:
1. Synthetic silicone monomer: The manufacture of silicone resin first requires the synthesis of silicone monomer, usually using chlorosilane, silanol, silane and other compounds as raw materials, through chemical reaction to synthesize silicone monomer.
2. Polymerization reaction: Add silicone monomer to the reactor, add catalyst and solvent, polymerization reaction. The conditions of polymerization reaction include temperature, pressure, reaction time, etc. Different silicone resins need different reaction conditions.
3. Adjust the molecular weight: the molecular weight of the silicone resin obtained after the polymerization reaction is usually higher, and the molecular weight needs to be controlled by adding diluent and adjusting the reaction conditions.
4. Refining and processing: After adjusting the molecular weight, the silicone resin needs to be refined and processed, including filtration, defoamer, drying and other steps to obtain high purity and high quality silicone resin products.
5. Packaging and storage: Finally, the silicone products are packaged and stored to ensure the quality and stability of the products.
