The period of time during which paint remains useful after its original package has been opened or after a catalyst or other additive has been incorporated. Also known as spreadable life; usable life.

pot life

1. The period of time during which a thermosetting plastic or rubber composition remains suitable for its intended use after mixing with a reaction-initiating agent; working life.
2. The length of time a paint material is useful after its original package is opened, or after catalyst or other ingredients are added; also called usable life, spreadable life.
