tesa HAF® 9402

125µm amber reactive HAF mounting tape

Product description

tesa HAF® 9402 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® 9402 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® 9402 reaches:

¹ Very high bonding strength
¹ High temperature resistance of up to 350°C
¹ Excellent chemical resistance
¹ Resistance against oil and solvents
¹ Bonds remain flexible and elastic

Processing:

1.Pre-lamination:
tesa HAF® 9402 is laminated 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 synchronizer rings:

¹ Temperature: 180 – 230°C
¹ Pressure: > 6 bar
¹ Time: 3 min
3. Tempering (optional)
To reach 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 aluminum 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.
