Technical Details & Test Data

Processing Parameters

This IROSTIC grade can be used as a 2-component system in combination with our IRODUR product range.

  • Clean and dry parts to be bonded.
  • If possible, roughen the two surfaces using abrasive material.
  • Apply a thin layer of adhesive solution.
  • Dry surfaces for approx. 30 min to allow solvent evaporation.
  • Activate both surfaces by warming up to 25 - 40°C.
  • Press surfaces together for 30 seconds.
  • The bonding is stable after approx. 1 minute.
  • Full bonding strength will be reached after 24 hours.
  • Please note that the procedure described here is for the adhesive solution prepared with the IROSTIC.
