Feature
200 µm amber reactive HAF mounting tape
tesa® HAF 8401 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.
200 µm amber reactive HAF mounting tape
It is suitable for bonding of all thermal resistant materials such as metal, glass, plastic, wood and textiles.
1 High-strength splicing (overlap splice)
1 Structural bonding
1 Magnet bonding in electric motors
1 Friction liners for clutches
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.
