tesa HAF® 8405
30µm/1.1 mils 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/194° F 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:
- Very high bonding strength
- High temperature resistance
- Excellent chemical resistance
- Bonds remain flexible and elastic
Product details and specifications
Application Fields
It is suitable for bonding of all thermal resistant materials such as metal, glass, plastic, wood and textiles.

Additional Info
Processing:
1.Pre-lamination:
tesa HAF® 8405 is laminated before curing. For this process we recommend a temperature between 120 °C/248 °F and 140 °C/284° F.
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:
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/248 °F; 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.

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:
- Temperature: 180 – 230 °C (356-446 °F)
- Pressure: > 8 bar
- Time: 3 min – 30 min
