Joining Process
Information
Adhesive must be free of damage. Deformed adhesive must not be used.
- Prepare cartridge -A. B-
.
Cartridge
- 1.1 Pierce the membrane in the nozzle connection -X- using > VAS 221 005 - cartridge opener-1- . Remove flanged cover on end of cartridge -Y- with > VAS 221 005 - cartridge opener-1- .
- 1.2 Clean > VAS 221 005 - cartridge opener-1- after opening an individual cartridge.
- Screw both cartridges -A, B-
onto mixing nozzle -1-
.
Cartridges
Information
- Adhesive cartridges must only be used with piston-driven applicator guns.
- In the case of piston-driven processing guns with compressed air, the pressure must be at least 4.5 bar/66 psi.
- Insert mixing cartridge into the > VAS 5237 - double cartridge gun
.
Dual-cartridge gun
- 3.1 Move pressure piston back fully.
- 3.2 Insert double cartridge -A, B- into the bonding gun -1- .
- Press out adhesive components.
Adhesive coming out
- 4.1 Actuate the valve -Arrow- and allow the pressure pistons to move out slowly until both adhesive components emerge at the mixing tube.
- 4.2 Wipe off emerging adhesive components.
- Screw processing nozzle -1-
onto the cartridge nozzle -2-
.
Processing nozzle
- Align processing nozzle.
Direction of processing nozzle
Information
- In this position, the closed surfaces must be visible at the horizontal mixing nozzle from above and below and the mixing blade of the mixer insert from the sides.
- 6.1 Turn the processing nozzle on the mixing nozzle until the illustrated position is reached.
Information
Processing time
- The processing time of the adhesive at room temperature (23°C) is 10 min. The adhesive must be applied and the component must be joined within this time.
- To ensure that the substance is completely mixed, apply a bead of fresh adhesive that is approx. 10-20 cm long to a piece of cardboard before using it.
- Also apply a bead of adhesive approx. 10 cm long to a solid surface to test it.
- One adhesive set contains 6 m of adhesive bead. Have several adhesive sets ready if necessary.
- Mix adhesive components.
Valve
- 7.1 Actuate the valve -Arrow- and allow the pressure pistons to move out slowly until the adhesive is visible in the application tube.
Information
- When applying adhesive to a vehicle window, make sure there is a gap of at least > Required value 5 mm between the adhesive bead and seal profile.
Information
- In addition to this service information, observe the relevant job descriptions for body repairs!
- Apply adhesive to component.
- Bond component to the body.
