Epoxy Resin vs UV Resin
Epoxy Resin vs UV Resin: What’s the Difference?
If you've been exploring the world of handmade resin art, you've likely come across two main types: epoxy resin and UV resin. Both are used by artisans, but they have very different properties, applications, and results. Here's a clear breakdown.
What Is Epoxy Resin?
Epoxy resin is a two-part system — a resin and a hardener — that cures through a chemical reaction when mixed together. It's self-curing, meaning no special equipment is needed. Cure times range from 24 to 72 hours depending on the formula and environment.
Best for: Large pours, deep castings, trays, coasters, and decorative pieces that require depth and volume.
What Is UV Resin?
UV resin is a single-part resin that cures rapidly — within minutes — when exposed to ultraviolet (UV) light from a UV lamp. It requires no mixing and is ideal for small, thin applications.
Best for: Jewelry, small embellishments, thin coatings, and quick-turnaround projects.
Key Differences at a Glance
| Feature | Epoxy Resin | UV Resin |
|---|---|---|
| Cure Method | Chemical reaction (self-curing) | UV light required |
| Cure Time | 24–72 hours | 1–5 minutes |
| Pour Depth | Deep pours possible | Thin layers only |
| Cost | More economical at scale | More expensive per oz |
| Best Use | Trays, coasters, large art | Jewelry, small details |
| UV Yellowing Risk | Low (with UV-resistant formula) | Higher over time |
Why We Use Epoxy Resin at Trayz N' Beyond
For our flight trays, coaster sets, and lamp bases, epoxy resin is the clear choice. It allows us to create deep, layered pours with rich color, embedded elements, and a glass-like finish that simply isn’t achievable with UV resin at our product scale. Combined with UV-resistant formulas, our pieces are built for both beauty and longevity.
