Recently I was gluing a few pen blanks, using Devcon 4 ounce bottles of Two Ton Epoxy. The red bottle flowed like it should and clear. Turned the blue bottle upside down and it was like cold molasses. OK, put the bottle in warm water until it completely softened. But it had a grainy texture when squeezed on paper for mixing. I sent an email to customer service at Devon for their specific product and described the problem as I did here. All I got were links to a bunch of topics that didn't address my problem and a solution. I like TT epoxy as it has a long work time, allowing me to glue 3-4 tubes at a time. Had the five minute stuff but it sets up too fast for me plus I would need to mix a batch for each pen. Now...anyone have any suggestions? Thanks.

John, not an expert on Epoxy by no means, but after useing the stuff for 20 years I've seen no difference in vicosities between both A & B bottles. After all, they need to be thinner because one has to mix them. Call Devon again and ask to speak for someone in the technical department. Their quality control should be able to tell you right away about the viscosities of both. I personally use J & B Weld epoxies and usually glue 4-5 pen tubes up with one mixing with time to spare before the stuff starts to set up.

Bob, there is no phone number for Devcon customer service, only an email inquiry.

Yes, crystallized epoxy will still work if properly warmed back to a liquid state, as crystallization is a natural occurrence often triggered by low temperatures and does not degrade the material's performance properties.

To restore usability:
  • Heat the resin: Submerge the stiff bottle in a hot water bath (approx. 122°F to 140°F or 50–60°C) or use a microwave for short intervals (5–10 seconds) until the crystals dissolve.
  • Mix thoroughly: Ensure the heat is evenly distributed and all granules are melted before mixing the resin with the hardener.
  • Verify cure: Perform a small test mix on scrap material to confirm it hardens correctly, as age or contamination can occasionally affect curing even if the epoxy was merely crystallized.
While some users report older epoxy becoming brittle or failing to cure fully, warming crystallized epoxy generally restores its original flow and strength, making it suitable for most applications.
