tesa® 8466

150µm double sided translucent HAF non-woven mounting tape



Product description

tesa® HAF 8466 is a copolyester based thermoplastic bonding film. This translucent double sided tape has a non-woven backing. It is protected by s strong paper liner.

tesa® HAF 8466 is free of halogen and compliant with current ROHS standards.

At room temperature tesa® HAF 8466 is not tacky. It is activated by heat while applying slight pressure.

Special Features:

1 Reliable and ageing resistant bonds
1 Very high performance on large bonding areas
1 Low bonding pressure required
1 Low oozing ratio & excellent process ability due non-woven backing
1 Excellent shock resistance
1 Bonds remain elastic

Main applications

tesa® HAF 8466 is especially recommended for bonding of metal components to various plastic or metal surfaces, e.g. SUS or AL to PC, PMMA or ABS:

1 Bonding of decorative metal components
1 Bonding of logo to housing
1 Fabric bonding in accessories

Additional Info

Technical recommendations: tesa® HAF 8466 is not self adhesive. It is activated by heat while applying slight pressure.

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:
  • Temperature¹ 100 – 140 °C
  • Pressure² 2 – 5 bar
  • Time 2 – 5 s.

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

Machine setting:
  • Temperature¹ 125 – 150 °C
  • Pressure² 2 – 5 bar
  • Time 5 – 15 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 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: AL & PC test specimen / Bonding conditions: Temperature = 150 °C; Pressure = 5 bar; Time = 7 sec).

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