Working With PORSCHE 2-Component Window Adhesive: Hardening
WARNING: This page is about a different car, the 2023 Porsche Cayenne, 2022 Porsche Cayenne, 2021 Porsche Cayenne, and 2020 Porsche Cayenne. However, it is still accessible from the selected car via links, so may be relevant.
The Porsche 2-component window adhesive hardens in the following temperature range:
> Minimum temperature 18°C
> Maximum temperature 35°C
Hardening can be accelerated by heat (e.g. using a painting booth). The bead of adhesive you pressed out earlier can be used to check whether the adhesive has hardened properly.
Do not put pressure on bonded parts until the required assembly strength is reached.
