Photovoltaic solar power generation is an important source of clean energy at present. In the production of photovoltaics, it is necessary to use sealant to seal the frame and bond the junction box, use sealing adhesive to protect the internal components of the junction box, and use structural adhesive to fix waterproofing during installation. Due to the special nature of the usage environment, it is required that the organic silicone used must strictly have excellent weather resistance and high and low temperature resistance to ensure the long-term stable operation of photovoltaics.
