If you want your epoxy resins A and B to last as long as possible, it might be tempting to try thinning them—however, this is not advisable. Here’s what you need to know about thinning epoxy for storage and how to keep it at its best.
Why Thinning Epoxy Is Not Recommended
Adding solvents or thinning agents to epoxy resin can disrupt its chemical structure, leading to poor curing or even failure when you finally use it. Over time, thinned resins may not harden properly, resulting in tacky or soft finishes. Your projects can suffer from bubbles, uneven texture, or a lack of structural integrity. Keeping your resin pure ensures that when you’re ready to work, you can trust your results.
The Best Way to Store Epoxy Resins
Rather than trying to modify or thin epoxy, proper storage is key. Always keep unopened and partially used containers tightly sealed. Store your resin and hardener in a cool, dry environment away from sunlight and extreme temperatures. If you’ve selected an epoxy like Epoxytable 10-Ten, following correct storage practices ensures the resin retains its excellent casting properties even after several months.
When This Matters Most
This is especially important for anyone buying resins in bulk for larger projects, such as river tables or detailed artwork, and for craftspersons who may not use their supplies all in one go. Proper storage keeps your investment in premium materials safe for whenever inspiration strikes.
