Elastic adhesive | Highly heat-resistant Elastic AdhesiveSX7700

Features

  • This highly heat-resistant adhesive can be used at temperatures of up to 150°C, maintaining stable adhesive properties even in harsh temperature environments.
  • Contains no low-molecular siloxanes, which can cause electrical contact failure.
  • Adheres well to various materials, including engineering plastics such as PBT.
  • Environmentally friendly, solvent-free adhesive that is safe to work with.
