Product information

tesa ® HAF 8490

Heat activated film

Product description

tesa ® HAF 8490 is a thermosetting single-sided adhesive film (brown) that is based on phenolic resin and nitrile rubber. It has a white cotton fabric carrier.

At room temperature tesa ® HAF 8490 is not tacky. It is activated for pre-lamination by heat and starts to become tacky at 90°C. In a second application step heat and pressure is applied over a certain period of time.

After curing tesa ® HAF 8490 reaches a very high bonding strength, high temperature stability and excellent chemical resistance. Because of the rubber components HAF 8490 remains flexible and elastic.

tesa ® HAF 8490 can easily be slit and die-cut.

Main applications

It is suitable for bonding of all thermally resistant materials such as metal, glass, plastic, wood and textiles.
