NOTE: TECHNICAL INFORMATION
Adhesive hardening time K2:
The clamping tools must remain in the vehicle for at least 1 h.
Do not shift the vehicle during this period. Only then is it permitted to proceed with subsequent installation work.
Check whether the reference bead has hardened after 2 hours hardening time (15 - 38°C).
After bonding, the vehicle must remain parked for at least 12 hours at room temperature (15 - 38°C).
The vehicle is then ready for operation.
Observe the hardening time of the adhesive.
Level out leaked adhesive in the area (1) at all 4 corners of the roof outer skin (2) by spreading.
No sharp edges should be left behind, otherwise the subsequent bonding of the front and rear windows could show a leakage.
Spread excess adhesive in roof trim strip channel. The mounting surfaces of the mounting elements of the roof trim strips must not be coated with adhesive.
Remove excess adhesive. For that do not use any cleaning agent or solvent!
