Processing:
1. Pre-lamination:
tesa HAF® 9402 is laminated to the first substrate before curing. For this process we recommend a temperature between 90 °C and 140 °C.
2. Bonding:
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: 3–30 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: temperature = 120 °C; pressure = 10 bar; time = 8 min).
To reach maximum bonding strength surfaces should be clean and dry. Storage conditions according to
tesa HAF® shelf life concept.
