Product information

tesa HAF® 58469

10µm black reactive HAF mounting tape



Product description

tesa HAF® 58469 is a reactive heat activated film based on phenolic resin and nitrile rubber. This black double sided tape has no backing. It is covered by a PET double liner solution.

tesa HAF® 58469 is free of halogen and compliant with current RoHS standards.

At room temperature tesa HAF® 58469 is not tacky. It is activated by heat and pressure applied during the assembly process.

Special Features:

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

Main applications

tesa HAF® 58469 is especially recommended for bonding of metal components to various plastic or metal surfaces, e.g. SUS or AL to PMMA, PC or ABS:

  • Constructive bonding inside electronic devices
  • Button fixation
  • Camera lens and bezel mounting
  • Bonding of decorative metal components
  • FPC mounting

Additional Info

Technical recommendations:
tesa HAF® 58469 is not self adhesive. It is activated by heat and pressure over a certain interval. The following values are recommendations for bond line parameters to start with.

1. Pre-lamination:
During pre-lamination, the adhesive tape is laminated onto the metal substrate. 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.

setting:
  • Temperature¹ 95-120 °C
  • Pressure² 2-6 bar
  • Time 3-10 s

2. Bonding:
Remove the liner from tape after pre-lamination step. Place the plastic part onto the metal component. Apply sufficient temperature while applying pressure for the bonding time to reach sufficient bonding strength.

setting:
  • Temperature¹ 120-250 °C
  • Pressure² 5-30 bar
  • Time 5-180 s

To achieve optimum performance a cooling step (while applying pressure) directly after the bonding step is recommended.

¹ ‘Pre-lamination’ and ‘Bonding’ temperature refer to the data that is measured in 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.
