Pot life describes the period of time over which a reactive two-part material has the right properties for being successfully processed. It depends on different factor, for example the mixing ratio or the temperature of the material during the dispensing process.
Beyond pot life, the viscosity of the material increases and so does the pressure in the mixer. This influences the whole metering and mixing process. The material becomes too thick and increasingly difficult to meter. In the worst case, the processing has to be stopped and the machine to be cleaned because the material has hardened. Because of this, it is important to monitor the pot life during breaks in the metering process.
