Pot life

Under pot life is meant the workability of reactive materials such. B. Adhesive . It is sometimes also called the service life. It is the time between the mixing of a multi-component substance and the end of its workability, i.e. the period of time in which the substance can still be removed from the pot and processed. The end of the pot life is usually indicated by a significant increase in viscosity , which prevents further processing.

The pot life depends on the chemical properties of the substance and the environmental conditions. The indication of the pot life of a substance (e.g. an adhesive) is only meaningful and meaningful with additional indication of the quantity, mixing, ambient climate (temperature and humidity) and vessel shape. The pot life is usually directly related to the gel time .

Very often the term “drip time” is wrongly used, which suggests that it stems from the increase in viscosity, during which the dripping ability of a thin-bodied substance decreases.

The pot life is used for (selection):

• Adhesives
• Synthetic resins
• Lacquers
• Colours
• plaster
• mortar
