tesa HAF® 8401

Processing:
1.Pre-lamination:
tesa® HAF 8401 is laminated before curing. For this process we recommend a temperature between 120 °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:

Splicing application:

¹ Temperature: 120-220 °C

¹ Pressure:>2bar

¹ Time: 15 – 90 s.
Friction liners for clutches:

¹ Temperature: 180 – 230 °C

¹ Pressure: > 8 bar

¹ Time: 3 min – 30 min
Magnet bonding:

¹ Temperature: 140 – 180 °C

¹ Pressure: > 6-10 bar

¹ Time: 2 min - 5 min
Structural bonding:

¹ Temperature: 180 – 220 °C

¹ Pressure: > 10-15 bar

¹ Time: > 3 - 30 min

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.
