The basic structural unit of organosilicon products is silicon-oxygen chain, and the side chain is all kinds of organic groups connected with silicon atoms. Therefore, in organosilicon contains both "organic groups" and "inorganic structure", this special structure makes it set the characteristics of organic and inorganic functions in a body. Silicone resin is a kind of highly branched polysiloxane prepolymer which can be further cured into an insoluble and unfused solid by heating. Silicone both with the characteristics of inorganic materials, organic resin has excellent heat resistance, weather resistance, electrical insulation, hydrophobic and resistance to chemical reagent, such as performance, at the same time can obtain colorless, transparent and has good adhesion and abrasion resistance of the coating, so in the special coatings industry occupies an important position, mainly used for high temperature resistant coatings, weather resistance coatings, hydrophobic coatings, etc.
