tesa® HAF 8401 Heat activated film (75.0mm x 25.00M) brown

tesa® HAF 8401 is a double-sided thermosetting brown adhesive film, without backing, based on phenolic resin and nitrile rubber.

At room temperature tesa® HAF 8401 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 8401 reaches a very high bonding strength, high temperature stability and excellent chemical resistance. Because of the rubber components tesa® HAF 8401 remains flexible and elastic.

tesa® HAF 8401 is supplied with a strong paper liner and can easily be slit and die cut.
