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:
- Temperature¹ ≥120 °C
- Pressure² ≥5 bar
- Time ≥5 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
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.
