Definition of Pot Life

Pot life or working life is the available time to process a reacting thermosetting formula.

Once the ambient cure temperature is reached and the crosslinking reaction begins, pot life describes the time available before the mixture becomes intractable or otherwise difficult to process.
For example, the pot life of a coating is the time during which the viscosity remains low enough to allow for easy brushing or spraying. In a molding compound, the working life represents the amount of residence time available in the molding machine before the material must be injected into the mold in order to have trouble-free molding and/or a defect-free part
