Silicone resin has the advantages of high temperature resistance, weather resistance and corrosion resistance, and is widely used as high temperature and corrosion resistant coatings. Traditional silicone resin systems usually use linear polysiloxane as an active diluent or add organic solvents to dilute the viscosity for processing, but linear polysiloxane's long chain is easy to tangle, with the passage of time, the viscosity has a tendency to increase, and it is difficult to use in the later period. Hyperbranched resin has a highly branched elliptic structure, high solubility, low viscosity, excellent fluidity, and good viscosity stability. Hyperbranched resins often contain little or no volatile organic solvents and have the advantages of low toxicity, environmental protection and low cost.

Silicone resin is widely used in heat resistant coating. For example, silicone modified epoxy resin is applied to the surface treatment of pipeline steel plate substrate to improve the heat resistance of coating. A modifier solution consisting of hydrofluorosilicone oil (HFSO), tetramethyltetravinyl cyclotetrasiloxane (V4) and hydrophobic SiO2 is also available to construct a superhydrophobic silicone resin coating on the surface of a wood substrate with good wear resistance, including resistance to finger touch, tape peeling and sandpaper wear. However, most of the coatings reported at present require high temperature during coating or add solvents to reduce the viscosity of the resin to facilitate construction, which is not only difficult to construction, but also produce toxic gases, resulting in environmental pollution. In response to these problems, solvent free hyperbranched silicone resin (HSR) came into being, and the commercially available methyl silicone resin (SH9502) was modified with HSR. By changing the amount of HSR added, the viscosity of the blended resin was regulated, the heat resistance of the resin was improved, and the mechanical properties and contact Angle of the resin were improved. Finally, a high temperature resistant coating with better comprehensive properties than SH9502 was prepared.
