Working With Body Foam Filler: Hardening
WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2021 Porsche 718 Cayman, 2021 Porsche 718 Boxster, 2020 Porsche 718 Cayman, 2020 Porsche 718 Boxster, and 2019 Porsche 718 Cayman. However, it is still accessible from the selected car via links, so may be relevant.
The body foam filler used hardens at temperatures of between > Minimum temperature 15°C and > Maximum temperature 28°C .
The chemical reaction is essentially complete after approx. 30 minutes. The hardening time will be longer at low temperatures and shorter at high temperatures.
Do not put pressure on bonded parts until the required assembly strength is reached.
