Adhesive quantities:
Approx. 1 1/4 adhesive cartridges are needed to cement 7 Series windscreens.
In the case of hot cementing (with accelerator), the missing residual bead is applied from a second adhesive cartridge (not contained in the repair kit) but while cold and without accelerator (bubbling).
Minimum hardening period is thus not increased.
IMPORTANT:
If a second cartridge is required for cementing:
- First apply cold adhesive to cowl panel at bottom (skin formation time)
- Accelerator from repair kit must not be used with the second cartridge (bubbling)
Bubbling results in leakage and insufficient bonding strength (torsional rigidity, passenger airbag).
