Cure times The amount of time it takes for
the glue to form its maximum bond. This can vary from as
few as 24 hours for white or yellow glue to as long as a
week or more for some epoxies.

Shelf life: Good glues do go bad. "Shelf
life" refers to the period of time that glue remains
useable. White, yellow and polyurethane glues last for
about a year if properly stored in airtight containers.
Hot-melt sticks and epoxies remain useable for many years.
Improper storage can cause glue to spoil prematurely. (For
this reason, buying a larger container isn't always a
bargain.) As a rule, if the working properties of a
particular glue seem abnormal, don't use it.
Pot life: For those glues that require
mixing, "pot life" refers to the time you have to apply the
glue to your work after you have mixed it. Epoxies have pot
lives that vary from five to 30 minutes; if you need more
time, lowering the glue's temperature will extend its pot
life.
