Product description
tesa HAF® 8490 is a reactive heat activated film based on phenolic resin and nitrile rubber. This amber single sided tape has a cotton fabric backing. It can easily be slit and die cut.
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:
- Very high bonding strength
- High temperature resistance
- Excellent chemical resistance
