1.1 Basic properties of silicon
Silicon is one of the most abundant elements in nature, accounting for about 25.7 percent of the mass of the Earth's crust, second only to oxygen. There is no free pure silicon in nature, but it occurs in the form of oxides, such as silica and silicate. As the main structure of polysiloxane, Si-O-Si bond appears in common inorganic materials such as sand, stone, glass, ceramics, and quartz.
1.2 Basic properties of siloxane
The Si-O-Si bond length of siloxane is long, the bond Angle is large, and it is easy to rotate. The steric hindrance of the opposite side chain rotation is small, the molecular volume is large and the cohesive energy density is low, which reduces the steric hindrance and makes the free rotation of the side groups easier, and it has the characteristics of low glass transition temperature, low surface tension and surface energy, low dissolution parameters and low dielectric constant.
Polysiloxane resin is a semi - inorganic, semi - organic structure of polymer compounds, thus both organic polymer and inorganic polymer characteristics. These properties include high and low temperature resistance, weathering resistance, electrical insulation, ozone resistance, hydrophobic, flammable, physiological inert, oil resistance, solvent resistance, radiation resistance.
1.3 Application of silicone resin
The most classic practical application is the inorganic zinc rich coating, its base material is composed of silicate ester, the coating as an anticorrosive coating can provide up to 50 years of service life. The epoxy-silicone system as a surface coating has been used for more than 20 years due to its excellent weather resistance and corrosion resistance.
Other Applications: Primers, Heat Resistant Coatings, Industrial Maintenance Coatings, Hygiene (Antibacterial) Coatings, Marine Coatings, Insecticidal Coatings, Antifouling Coatings, Antiwear Coatings, Automotive Varnishes, and Architectural Coatings.
