tesa HAF® 8402

Technical recommendations tesa HAF® 8402 is not self adhesive. It is activated by heat and pressure over a certain interval. The following values are recommendations for machine parameters to start with. Please note that optimum parameters strongly depend on the type of machine, particular materials as well as customer requirements. 1.Pre-lamination: tesa HAF® 8402 is laminated before curing. For this process we recommend a temperature between 120°C and 140°C. 2.Bonding: The bonding conditions temperature, pressure and time depend on the application. Following parameters can be regarded as a guideline: Splicing application: Temperature: 120-220 °C Pressure: >2bar Time: 15 – 90 s. Friction liners for clutches: Temperature: 180 – 230 °C Pressure: > 8 bar Time: 3 min – 30 min Magnet bonding: Temperature: 140 – 180 °C Pressure > 6-10 bar Time: 2 min - 5 min Structural bonding: Temperature: 180 – 220 °C Pressure: > 10-15 bar Time: > 3 - 30 min Bonding strength values were obtained under standard laboratory conditions. Value is guaranteed clearance limit checked with each production batch (Material: Etched aluminium test specimen / Bonding conditions: Temp. = 120 °C; p = 10 bar; t = 8min). To reach maximum bonding strength surfaces should be clean and dry.
