Introduction of Silicone Coatings
Silicone coating is a kind of polymer which is composed of alternately bonded silicon and oxygen atoms, and different organic groups are bonded with silicon atoms. It is a kind of coating with silicone polymer or its modified polymer as the main film-forming material. It has excellent heat resistance, cold resistance, corona resistance, radiation resistance, hydrophobicity, stain resistance, etc. In recent years, chemical corrosion resistance, electrical insulation and elasticity have developed rapidly in the modification and application of products.

1 Introduction:
Silicone coating is a kind of polymer which is composed of alternately bonded silicon and oxygen atoms, and different organic groups are bonded with silicon atoms. It is a kind of coating with silicone polymer or its modified polymer as the main film-forming material. It has excellent heat resistance, cold resistance, corona resistance, radiation resistance, hydrophobicity, stain resistance, etc. In recent years, chemical corrosion resistance, electrical insulation and elasticity have developed rapidly in the modification and application of products.
If silicone resin is used to form a layer of film material on the surface of buildings, it can effectively improve the weatherability (wind erosion resistance, rain immersion resistance and acid rain erosion resistance) of the building surface, and has a certain practical application value for high-end buildings, especially for the protection of ancient buildings. Silicone elastic latex architectural decorative coatings, easy to operate and control, stable product performance, good cohesion, aging resistance, weather resistance, impermeability and flexibility, to adapt to bad factors caused by wall cracking and seasonal typhoon, rainwater pressure penetration. Elastic-plastic silicone "three-proof" coating has good storage stability at room temperature. It can solidify into film at room temperature after adding drier. It can be used for moisture-proof treatment of capacitors, impregnation of ceramic porous materials and protective coating of petroleum instruments in electrical, electronic, petroleum and pharmaceutical industries. It can be used as protective material of QM cardiac pacemaker. Material, silicone modified polyurethane paint, etc.
2 Organosilicon resin:
Organosilicon resin is a highly cross-linked network structure of polyorganosiloxane, usually with methyl trichlorosilane, dimethyl dichlorosilane, phenyl trichlorosilane, diphenyl dichlorosilane or methyl phenyl dichlorosilane of various mixtures, in the presence of organic solvents such as toluene, water decomposition at lower temperatures, to obtain acidity. Hydrolysate. The initial product of hydrolysis is a mixture of cyclic, linear and cross-linked polymers, usually containing considerable hydroxyl groups. The hydrolysate is washed to remove acid, the neutral primary condensate is oxidized in air or further condensated in the presence of catalyst, and finally a highly cross-linked three-dimensional network structure is formed. Silicone resin has good properties, and its properties are compared with those of general oil-based resins as shown in the table below.
