Notes on component bonding with adhesive tape (4' Series coupe, convertible, and Gran Coupe sedan)

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. 4.1 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. 4.2 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.
