How long does it take epoxy to yellow?

Yellowing begins immediately when the resin is exposed to light though it may take time to become noticeable to the eye.

Why is my resin hardener yellow?

This yellowing is due to oxidation, a reaction with oxygen in the air which causes the amines in the hardener to discolor. As air exposure continues, this color will deepen over time, much in the way an apple or avocado will brown, once cut and exposed to air.

6 monthsThe hardeners for epoxy resins are the more concerning (though still long-lived) materials. It is suggested that most hardeners are used within a year closed, or 6 months if opened.
