tesa HAF® 9472

60µm amber reactive HAF mounting tape



Product description

tesa HAF® 9472 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 be easily slit and die cut.

At room temperature tesa HAF® 9472 is not tacky. It is activated by heat and starts to become tacky at 90 °C for pre-lamination.

After curing tesa HAF® reaches:

  • Reliable and ageing-resistant bonds
  • Extremely high performance, even on small bonding areas
  • Very low oozing ratio
  • Suitable for long-term applications that are exposed to heavy stress
  • Bonds remain flexible and elastic
  • Resistance against oil and solvents

Main applications

tesa HAF® 9472 is especially recommended for bonding of thermal resistant materials such as metal, glass, plastic and textiles.

  • Mounting of sensor plates

Additional Info

Processing:

1. Pre-lamination:
During pre-lamination, the adhesive tape is laminated onto the first substrate. For this process we recommend a temperature between 90 °C and 140 °C for 3 - 10 s and a pressure of 0.5 - 2.5 bar. This step does not affect the shelf life time of the adhesive tape. Pre-laminated components can be stored over the same period of time as the adhesive tape.

2. Bonding:
Remove the liner from the tape after pre-lamination. Position the second substrate and apply heat and pressure for the bonding. Following parameters can be regarded as a guideline:

  • Temperature¹ 180 - 230 °C
  • Pressure² >6 bar
  • Time 3 min

3. Tempering (optional)
To reach maximum bonding strength the bonded parts can be tempered at 180 - 230 °C for 30 - 60 min.

¹ ‘Pre-lamination’ and ‘Bonding’ temperature refer to the data that is measured at the bond line.
² ‘Pre-lamination’ and ‘Bonding’ pressure refer to the force that is transformed from jig surface directly to the bonding area.

Bonding strength values were obtained under standard laboratory conditions. (Material: etched aluminum test specimen / bonding conditions: temperature = 180 °C; pressure = 10 bar; time = 7 sec).

To reach maximum bonding strength surfaces should be clean and dry. Storage conditions according to tesa HAF® shelf life concept.
