    QUESTION:

    We have issues with crystallized epoxy: has the epoxy had “gone bad”?

     

    ANSWER:

    This question has come up so often, I have written an article to educate our customers about crystallization in epoxies including information on:

    • How this happens.

    • Why the epoxy is perfectly usable (it has not “gone bad”).

    • How they can easily return the epoxy back to its clear, liquid form.

    Crystallization in epoxies is such a common occurrence - hope you find the following answers and advice helpful!
