tesa HAF® 58473
80µm black reactive HAF mounting tape
Product description
tesa® HAF 58473 is a reactive heat activated film based on phenolic resin and nitrile rubber. This black double sided tape has no backing. It is protected by a strong paper liner.
tesa® HAF 58473 is free of halogen and compliant with current ROHS standards.
At room temperature tesa® HAF 58473 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

Additional Info
Technical recommendations:
tesa® HAF 58473 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.
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.
Machine setting:
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.
Machine setting:
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 at the surface of heating jig.
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.
