On this subject, we recommend asking the car manufacturer for new cars or the paint shop carrying out new or re-painting, as there can be significant differences in the curing time of paints.
This is decisively influenced by the composition of the paint, the time it remains in the drying chamber and the climatic conditions.
The reason for this is the chemical reactions that take place during the curing process, which are necessary for the paint to fully cure.
After painting, drying (evaporation of solvents) is completed after 30-45 minutes in the drying chamber and the paint has hardened to such an extent that it can no longer absorb dust particles. The subsequent hardening (formation of polymer chains) can take several weeks.
In any case, we recommend using a conservative curing time so that 100% curing is guaranteed.
