Additional Info
1. Pre-lamination:
tesa HAF® 9401 is laminated to the first substrate. For this process we recommend a temperature between 120 °C and 140 °C and a slight pressure of 0.5 - 2.5 bar for 3 - 10 sec.
2. Bonding:
The liner is removed from the tape after pre-lamination. The bonding conditions depend on the application. Following parameters can be regarded as a guideline:
1 Temperature: 180 – 230 °C
1 Pressure: > 8 bar
1 Time: 3 min – 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: Temp. = 120 °C; p = 10 bar; t = 8 min)
To reach maximum bonding strength surfaces should be clean and dry. Storage conditions according to tesa HAF® shelf life concept.
