Notes on component bonding with adhesive tape (M3 base, M3 Competition, M3 Competition M xDrive, M3 CS)

Unless specified otherwise in vehicle-specific or component-specific instructions, the following notes apply

Follow REPAIR NOTES 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
Auxiliary materials and tools
- CLEANING AGENT R1 OR CLEANING AGENT R2 .
- SIKA ACTIVATOR 205 .
- Fluff-free cleaning cloths
- Pressure roller
Preparations
- Remove all adhesive residue or clean new part thoroughly
- Clean the areas to be bonded immediately before bonding to remove silicone and grease residues
- Treat bonding on glass or painted surfaces with SIKA AKTIVATOR-205 .
NOTE: APPLY SIKA AKTIVATOR-205 extremely thinly. It must not be coated beyond the bonding surface
Note air drying time ≥ 1 minute
Bonding
1. Components without preassembled adhesive tape
  - Detach liner* from adhesive tape
  - Position adhesive tape on component and stick on
  - Press down adhesive tape over entire adhesive area
  - Continue with Point 4.2
  * Liner is the protective film on the adhesive tape
2. Components with pre-fitted adhesive tape
  - Detach liner* from adhesive side (if adhesive area is large, do not detach liner completely)
  - Align component in correct position on vehicle
  - Press down component over entire adhesive area
  Minimum contact pressure > 15 N/cm² (firm thumb pressure reaches approx. 35 N/cm² .)
  
  * Liner is the protective film on the adhesive tape
