Product descriptiontesa HAF® 9410 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® 9410 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® 9410 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
Main applicationsIt is suitable for bonding of all thermal resistant materials such as metal, glass, plastic, wood and textiles.
1 Friction linings for clutch discs
1 Friction linings for synchronizer rings
Shelf life time < 25°C
Type of adhesive
nitrile rubber / phenolic resin
Shelf life time < 15°C
Type of liner
Shelf life time < 5°C
tesa HAF® 9410 is laminated before curing. For this process we recommend a temperature between 90°C and 140°C.
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 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.
