Product information

tesa HAF® 8402

125µm amber reactive HAF mounting tape



Product description

tesa HAF® 8402 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® 8402 is not tacky. It is activated by heat and pressure applied over a certain period of time.


After curing tesa HAF® 8402 reaches:


  • Very high bonding strength
  • High temperature resistance
  • Excellent chemical resistance
  • Bonds remain flexible and elastic

Main applications

It is suitable for bonding of all thermal resistant materials such as metal, glass, plastic, wood and textiles.


  • High-strength splicing (overlap splice)
  • Structural bonding
  • Magnet bonding in electric motors
  • Friction liners for clutches

Additional Info

Technical recommendations tesa HAF® 8402 is not self adhesive. It is activated by heat and pressure over a certain interval. The following values are recommendations for machine parameters to start with. Please note that optimum parameters strongly depend on the type of machine, particular materials as well as customer requirements. 1.Pre-lamination: tesa HAF® 8402 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: Temperature: 120-220 °C Pressure: >2bar Time: 15 – 90 s. Friction liners for clutches: Temperature: 180 – 230 °C Pressure: > 8 bar Time: 3 min – 30 min Magnet bonding: Temperature: 140 – 180 °C Pressure > 6-10 bar Time: 2 min - 5 min Structural bonding: Temperature: 180 – 220 °C Pressure: > 10-15 bar 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 = 8min). To reach maximum bonding strength surfaces should be clean and dry.
