Product information "Tesa HAF 8401"
Product Description
tesa® HAF 8401 is a heat-activatable film based on nitrile rubber and phenolic resin. This amber-colored, linerless material is covered with a paper liner, making it easy to cut and punch. At room temperature, tesa® HAF 8401 is non-adhesive. The activation temperature for pre-fixing is approximately 90°C. In a second processing step, the product is applied under pressure and heat.
After full curing, tesa® HAF 8401 achieves extremely high bond strength.
-
Very high temperature resistance
-
Excellent chemical resistance
-
The adhesive joint remains elastic.
Main Applications
This material can be used for all materials with high heat resistance, such as:
- Metal
- Glass
- Plastic
- Textiles
- Bonding of magnets in electric motors
- Bonding of sliding bearings and brake pads
- Structural bonding

Processing
-
Pre-lamination:
tesa® HAF 8401 becomes tacky between approximately 90°C and 110°C. Recommended pressure: > 0.2 bar. -
Curing:
Bonding parameters—temperature, pressure, and time—depend on the application and the materials being bonded. As a guideline:-
Splicing applications:
-
Temperature: 120°C - 200°C
-
Pressure: > 2 bar
-
Time: 15 sec. - 30 min.
-
-
Bonding clutch linings:
-
Temperature: 180°C - 230°C
-
Pressure: > 6 bar
-
Time: 1 min - 30 min.
-
-
For maximum bond strength, surfaces should be clean and dry.
Storage Conditions In accordance with tesa® HAF durability concept.
