QUESTION:  

Can you use expired epoxy?

 

ANSWER:

Epoxy does have a shelf life and the physical properties will change over time. Epoxy manufacturers recommend you do not use epoxy that has reached its expiration date. If unusual circumstances require you to use expired epoxy, Fiber Optic Center recommends that you test the material before using it in your production process. Cure it to see if it sets as expected. However, it’s difficult to determine if it has, indeed, cured and set properly. To validate your epoxy curing process, we recommend following the Telcordia GR-326 adhesive testing standard (section 4.4.4.2). Finally, here is our favorite tip regarding using expired epoxy: When in doubt, throw it out!
