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.

Covestro says the new matrix material can be processed extremely cost-efficiently, thanks to its long pot life and rapid curing.
Application is aided by low viscosity, which assists in achieving a void-free cure, together with its extended working life which permits a manageable cure process based around a workable one-hour pot life with room temperature cure within 24 hours.
During application, it can be reagitated to reduce viscosity and improve workability time inside of its 70-minute pot life.
And most crucially, it ensures longer pot life due to limited cathode surface burn-off.
"Our new Joncryl FLX two-pack ink technology now allows converters the option to print with water-based inks that have a longer pot life and lower toxicity ratings than many two-pack water-based systems currently used for these high resistant applications," said Richard Grancike, industry manager--Printing & Packaging, Dispersions and Pigments for BASF in North America.
In addition, it has a pot life of one hour at room temperature and cures to a translucent elastomer without releasing any by-products.
