Do I need a UV lamp to cure it?

Yes. It cures under UV light, so a UV lamp is the reliable way to set it. Sunlight alone may not fully cure thicker pieces.

Can I use it for deep molds?

It works best in thin layers. For deep molds, pour in stages and cure each layer under the lamp.

How does it compare with two-part epoxy?

It needs no mixing and cures faster under a lamp, but two-part epoxy suits deep pours and longer working time better.

Will it yellow over time?

The resin is formulated for yellowing resistance, but long UV exposure and old stock can still discolor it. Store it sealed and away from light.

What is the shelf life?

About one year. Keep the bottle capped and out of direct sunlight to get the most from it.

Why is my piece still tacky?

It was likely under-cured. Cure longer under the UV lamp and let it cool before handling.

Our take on the LET'S RESIN 500g UV Resin

LET'S RESIN UV Resin is a clear, single-component resin that cures hard under a UV lamp, no mixing required. It is marketed as low odor, with an 85D scratch-resistant surface and under 2% shrinkage, plus yellowing resistance for jewelry and small castings. The 500g bottle suits frequent crafters who want a bulk supply for pendants and detailed work. Against two-part epoxy rivals it skips measuring and long cure times, but it needs a UV lamp and cures in thin layers, so deep pours are not its job.
