HAF® 9405 is laminated to the first substrate before curing. For this process we recommend a temperature between 90°C and 140°C.
The bonding conditions temperature, pressure and time depend on the application. Following parameters can be regarded as a guideline:
Friction linings for clutch discs:
- Temperature: 180 – 230°C
- Pressure: > 6 bar
- Time: 3 min
3. Tempering (optional)
To reach the maximum bonding strength the bonded parts can be tempered at 180 - 230°C for 30 - 60 min without pressure.
Bonding strength values were obtained under standard laboratory conditions. Value is guaranteed clearance limit checked with each production batch (Material: Etched aluminium test specimen / Bonding conditions: Temp. = 120°C; p = 10 bar; t = 8min).
To reach maximum bonding strength surfaces should be clean and dry. Storage conditions according to tesa
HAF® shelf life concept.
