Adhesive quantities

Approx. 1 1/4 glue cartridges are required to bond the windscreen on the following vehicles:

7 Series
5 Series from E60
X5
X3

In the case of hot bonding (with accelerator), the missing residual adhesive bead is applied from a second glue cartridge but while cold and without accelerator (formation of bubbles/blisters).

Minimum hardening time is thus not increased.

IMPORTANT: If a second cartridge is required for bonding:

First apply cold adhesive to cowl panel at bottom (skin formation time)
Accelerator from repair kit must not be used with the second glue cartridge (formation of bubbles/blisters)

Formation of bubbles/blisters results in leakage and insufficient bonding strength (torsional rigidity, front passenger airbag).

Effect of differing adhesive quantities:

ADHESIVE QUANTITIES EFFECT

Too little adhesive:	Too much adhesive:
Window glass rests too low in body aperture Strains/tensions may occur (window glass breakage) Insufficient squeezing of adhesive bead (leaking)	Window glass rests too high in body aperture Wind noise may occur Strains/tensions may occur (window glass breakage) Dirt contamination of add-on parts by emerging adhesive Adhesive on uninsulated strainer pressure lines of aerial(s) (interference of reception)
