Tesa 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:MetalGlassPlasticTextilesBonding of magnets in electric motorsBonding of sliding bearings and brake padsStructural bondingPropertiesAdhesion Strength(dynamic shear)12N/mm²Adhesion Strength(ppel-off)12N/mm²Technical PropertiesLiner TypeRelease paperThickness200 µmColorAmberAdhesiveNitrile rubber & phenolic resinCarrier MaterialNone 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. Larger quantities are available upon request.
