  & nbsp; & nbsp; & nbsp; Requirements for photovoltaic sealant



  & nbsp; & nbsp; & nbsp; From the perspective of its application environment, the adhesive used for solar photovoltaic modules is mainly used outdoors and must meet the differences in external geographical and climatic conditions, which puts forward the following requirements for performance characteristics:< br />


  & nbsp; & nbsp; & nbsp; 1. Good weather resistance: able to withstand high and low temperature environmental tests, such as in western provinces, hot and dry, and in southern provinces, high and humid, moisture-proof, and resistant to environmental corrosion< br />
  & nbsp; & nbsp; & nbsp; 2. Good resistance to UV exposure; Yellowing resistance; Good adhesion ability (under UV irradiation, rainstorm, strong wind, high and low temperature environment)< br />
  & nbsp; & nbsp; & nbsp; 3. Good combustion resistance; Resistance to mechanical shock, thermal shock, and earthquake resistance< br />


  & nbsp; & nbsp; & nbsp; Solar photovoltaic sealant mainly focuses on the encapsulation of photovoltaic cell modules, the packaging of photovoltaic frame modules, and the conductive bonding between solar cell silicon chips and conductive silver bars. The main adhesive points for ground photovoltaic modules include frame sealing, junction box bonding, junction box sealing, busbar sealing, and bracket bonding. The required performance of each adhesive point will vary greatly.
