Feature
200 µm amber reactive HAF mounting tape
tesa®8401 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.
Application
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
Additional Information
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.
