What is Pot Life or useful life?
is a term used for two-component (or multi-component) coatings that cure through a chemical reaction (such as Polyurethanes).
These systems consist of a base component (Part A) and a catalyst or hardener component (Part B). When these components are mixed together, a chemical reaction begins that causes the paint to dry.

Factors affecting pot life?
– Hardener or Catalyst
Pot life depends on the type of hardener or catalyst used, which can increase or decrease pot life.
– Temperature
As temperature increases, reactions occur faster, resulting in a reduced pot life. A low ambient temperature helps to reduce the mixture’s temperature, slow down the polymerization reaction, and consequently increase the pot life.
How can pot life be extended?
- Temperature control
- Use of small packaging
- Use of a slower hardener
- Store paint in a cool place away from direct sunlight.
