Product information "Tesa® HAF 8490 315µm single-sided heat-activated film (HAF) with fabric carrier"
Product Description
tesa® HAF 8490 is a single-sided heat-activatable film based on nitrile rubber and phenolic resin, with a white cotton fabric as the carrier material.
The product is non-adhesive at room temperature, making it easy to cut and punch. The activation temperature for pre-fixing is approximately 90°C. In a second processing step, the product is applied under heat and pressure.
After full curing, tesa® HAF 8490 achieves extremely high bond strength as well as excellent temperature and chemical resistance. The adhesive joint remains elastic.
Main Application
Endless bonding of temperature-resistant materials such as fiberglass, metallic, and textile substrates.

Processing
-
Pre-lamination:
tesa® HAF 8490 becomes tacky between 90°C and 110°C.
Recommended pressure: 2 bar -
Curing:
Bonding parameters—temperature, pressure, and time—depend on the application and the materials being bonded. As a guideline:-
Splicing Application:
-
Temperature: 120°C - 200°C
-
Pressure: > 2 bar
-
Time: 15 sec. - 90 sec.
-
-
For maximum bond strength, surfaces must be free of dust and dry.
Storage Conditions In accordance with tesa® HAF durability concept.
