What does pot life refer to in painting?

Pot life refers to the duration of time that a mixed coating material can be effectively used before it begins to harden or lose its usability, particularly following its induction period. This is especially relevant for two-component systems, such as epoxies and polyurethanes, where the mixing of components initiates a chemical reaction leading to curing.

During pot life, the coating maintains its workability and adhesion properties, allowing painters to apply it effectively. After the pot life expires, the material may become too viscous or set too firmly, making it unsuitable for application. Understanding pot life is crucial for painters to ensure that they are working with the coating while it is still usable, thus preventing waste and ensuring the quality of the finish.
