tesa HAF® 58451
30 μm black electrically conductive (XYZ) reactive HAF mounting tape
Product description
tesa HAF® 58451 is a reactive heat activated film based on phenolic resin and nitrile rubber with electrically conductive properties. This black double sided tape has no backing. It is protected by a 50 μm PET liner.
At room temperature tesa HAF® 58451 is not tacky. It is activated by heat and pressure applied during the assembly process.
Special features:
- Extremely high performance, even on small bonding areas and thin design gaps
- Excellent electrical conductivity in XYZ-direction
- Superior anti-repulsion properties even at elevated temperatures
- Outstanding chemical resistance
Product details and specifications
Application Fields
tesa HAF® 58451 is especially recommended for bonding of various metal surfaces, e.g. SUS or AL.
- Grounding applications with structural bonding requirements
- Narrow and small bonding areas but still need very strong bonding strength
- High repulsion force applications such as curved or bended bonds
- Grounding applications exposed to high temperature and humidity

Additional Info
Technical recommendations: tesa HAF® 58451 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 tape is laminated onto one component.
Setting:
2. Bonding: Remove the liner from the tape after pre-lamination step. Place the pre-laminated component onto the substrate to bond with. Apply sufficient temperature while applying pressure for the bonding time to reach sufficient bonding strength.
Setting:
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: SUS test specimen / bonding conditions: temperature = 180 °C; pressure = 30 bar; time = 30 sec). To reach maximum bonding strength surfaces should be clean and dry.
1. Pre-lamination: During pre-lamination, the tape is laminated onto one component.
Setting:
- Temperature¹: ≥120 °C
- Pressure²: ≥5 bar
- Time: 5-10 s
2. Bonding: Remove the liner from the tape after pre-lamination step. Place the pre-laminated component onto the substrate to bond with. 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 s – 3 min
