General requirements for applying the adhesive bead

Note In order to ensure for the homogeneous properties of the dual component mixture, apply a bead -a- with 10 cm to a clean surface and dispose of the first piece of the product.

  • The sleeve -2- must rest flush.
  • The -Arrow- indicates the direction of travel.
  • The diameter of the adhesive bead -1- will depend on the width of the hole in the applicator and the speed of application.
Caution

Risk of water penetrating via the panes bonded to the bodywork

  • To ensure the tightness between the windows and bodywork, cover the adhesive bead according to the following instructions:

Instructions for applying the adhesive sealing material (PUR).

Glazing

Note

  • If the window is not damaged, apply the material on the old adhesive bead previously cut-back. Follow the instructions accordingly
  • With a new window, apply the material on the primer layer.

 

  • In the intended area -1- of the window, using the cartridge gun - SAT 5350- or the double cartridge gun - VAS 5237- , apply an adhesive bead of the dual component adhesive - D 004 660 M2- .

Glazing

Note Always hold the gun at a right angles to the window.

WARNING

The glass must be fitted before 10 minutes elapse, as the adhesive properties of the adhesive sealing material (PUR) are reduced after that time.

Do not apply a very thick bead of glue nor press the glass hard against the bodywork flange, as the excess glue would be seen through the clearance, as there is no sealing lip.

For windscreens only

  • With the two suction holders - VAG 1344- , place the window on the body flange and press on evenly in the middle until the spacers are resting.
  • Check the clearances on the windscreen between the roof and upper struts A.
