Fortunately, it is much easier to remove bubbles from UV resin than from traditional resin. The reason for this difference is the drying time. Also called one-part resin, it doesn’t need to be mixed with any hardeners or other agents to work. It’s an easy-to-use, versatile resin that can be used in jewelry crafting, molds, casting, and nails. K. S. Toohey, N. R. Sottos, J. A. Lewis, J. S. Moore and S. R. White, Self-healing materials with microvascular networks, Nat. Mater., 2007, 6, 581–585, DOI: 10.1038/nmat1934.While not as dangerous as UVB light, UVA should still be used with caution and from a safe distance if possible. What Do You Need a UV Light Box For? If you are planning on doing a lot of UV resin projects, we suggest getting a decent quality UV lamp. While this is the easiest and cheapest way to cure resins using UV light, it’s far from the most efficient. To find the best UV light for curing resin, you’re going to have to get some extra equipment like a UV lightbox or flashlight.

Unfortunately, although it is non-toxic, one of the tradeoffs is a foul odor for this one, so keep that in mind. 15. Best UV Resin for Crafts Z. Liang, X. Wang, L. Feng and X.

Instead, all you need to do is expose it to a UV light or the sun and it will cure. Main Characteristics

In addition to protecting your skin from resin, be sure to also protect yourself from any UV light you’re using to cure your resins. UV light, while relatively harmless in small doses, can be very dangerous with long-term exposure. Its great consistency is perfect if you are just looking for the absolute clearest UV resin you can find. N. Wen, T. Song, Z. Ji, D. Jiang, Z. Wu, Y. Wang and Z.

Even if you don’t have a UV light box, you can use the natural UV light of the sun to cure your UV resins. Non-UV resins will still cure using this method, though you will have to wait for anywhere between 2-10 hours before it’s fully cured depending on the size of the project.
