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.
