Processing
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:
