What factors determine the length of cure for your tyre repair? Is heat quicker than chemical? Are there any repair practices that will speed up the cure?
We often get asked about curing times in tyre repair. Tyre size, injury location and site conditions all come into play. For example, unusually cold conditions will lengthen the required time to perform any type of cure.
The manufacturers of your cushion gum and patches will offer guidelines and you should note and abide by these.
Heat vs. chemical cures
As a general rule, a standard compound can be cured under heat and pressure at a rate of 3 minutes per mm of thickness.
Rapid cure compounds will reduce these times slightly to circa 2.5 minutes per mm of thickness.
Chemical cures on the other hand will need to be left for 48 to 72 hours to reach an optimum shore hardness.
Always consult the guidelines provided with the raw consumables in use for specific timings.
