Adhesive quantities

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2012 BMW 328xi, 2012 BMW 328i, 2011 BMW 328xi, 2011 BMW 328i, and 2010 BMW 328xi. However, it is still accessible from the selected car via links, so may be relevant.

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 APPLICATION REFERENCE CHART

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)
