EP138

EP122

EP170

EP610

EP811

Features

  • One-part heat curing adhesive
  • As a mixing process is not required, no measuring and mixing errors will occur, eliminating variations in bonding performance.
  • A wide variety of models, including a heat-resistant type, a low-viscosity type, and a low-temperature curing type, are available.
