Features

 

Advantages

  • After curing ,excellent weather resistance, good ultraviolet resistance, high bottom temperature resistance (also can be used in

extreme temperature)

  • High ultimate tensile strength to make it fully suitable for structural applications
  • Excellent mechanical properties
  • Construction is convenient

 

Application

   Used  for the elastic  structural bounding applications .such as glasses, metal etc

    Designed  specifically for the elastic structural bonding application ,such as glass, metal and other building components. It can also

be used as a stiffener component to bind building panel and other similar binding applications.
