51 00... Notes on component bonding adhesive tape
Unless specified otherwise in vehicle-specific or component-specific instructions, the following notes apply.
Follow REPAIR INSTRUCTIONS FOR BONDED GASKETS for rubber seals.
- General notes
- Bonding at room and object temperature of >+18 °C.
- Newly painted parts may only be bonded after a drying time of at least 24 hours.
- Optimal bonding/attachment to the background surface is achieved after approx. 48 hours. Components must not be exposed to mechanical strain beforehand (car wash, strength test, etc.).
- Do not touch bonding area.
- It is not the length of time that pressure is applied but rather the force of pressure applied that is crucial.
- Detaching the adhesive tape after pressing destroys the adhesive layer.
- After being pressed on gently, adhesive tape can be pulled off again up to 3 times.
- Auxiliary materials and tools
- CLEANING AGENT R1 OR CLEANING AGENT R2
