tesa HAF® 8405

30µm amber reactive HAF mounting tape

Product description

tesa® HAF 8405 is a reactive heat activated film based on phenolic resin and nitrile rubber. This amber double sided tape has no backing. It is protected by a strong paper liner and can easily be slit and die cut.

At room temperature tesa® HAF 8405 is not tacky. It is activated by heat and starts to become tacky at 90 °C for pre-lamination. In a second application step heat and pressure is applied over a certain period of time.

After curing tesa® HAF 8405 reaches:

¹ Very high bonding strength
¹ High temperature resistance
¹ Excellent chemical resistance
¹ Bonds remain flexible and elastic

Processing:

1.Pre-lamination:
tesa® HAF 8405 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:

Friction liners for clutches:

¹ Temperature: 180 – 230 °C
¹ Pressure: > 8 bar
¹ Time: 3 min – 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.
