The main reason silicone resins are resistant to UV radiation is the presence of silicon-oxygen bonds (Si-O) in their molecular structure, which give them the following properties:

High weather resistance: The high bond energy of the silicon-oxygen bond enables the silicone resin to maintain chemical stability for a long time under ultraviolet radiation. They resist oxidation and decomposition caused by UV rays, thereby prolonging the life of the coating film.

Ultraviolet absorption: The silicon-oxygen bond structure in the silicone resin can absorb part of the ultraviolet energy and convert it into heat instead of letting it directly act on the surface of the coating film. This can reduce the damage of ultraviolet rays to the coating film.

Reflection and scattering: The molecular structure of silicone resin can reflect and scatter ultraviolet rays, reducing the direct penetration of ultraviolet rays through the coating film. This scattering effect helps to disperse the energy of the ultraviolet light, reducing its impact on the coating film.

To sum up, silicone resin can resist ultraviolet radiation through its unique molecular structure, including the strength of silicon-oxygen bond and the characteristics of ultraviolet absorption, reflection and scattering. This allows the coating film to retain its appearance and performance for extended periods of time in outdoor environments, extending the life of the coating system.
