What is a UV Filter in Epoxy Resin?

Why UV Filters Matter in Epoxy Resin

Epoxy resin is susceptible to ultraviolet (UV) light, which over time can cause yellowing and cloudiness. To help mitigate this effect, some resin formulations include UV filters. These ingredients absorb or block portions of the UV spectrum, offering a layer of protection and helping projects keep their clarity and vibrance longer.

Choosing Epoxy Resins with UV Protection

When buying epoxy resin for jewellery, tables, or art, check the product information for mention of a UV filter or yellowing resistance. For example, ICreation Fast Epoxy Resin and One-2-One Epoxy Resin both feature UV filtering, giving added confidence if your work will be displayed in daylight.

• Store finished pieces away from direct sunlight when possible.
• Consider layering a UV-resistant varnish for additional support, especially on wearable items.

When UV Protection is Important

UV filtering in resin is especially valuable for projects that will be regularly exposed to natural or artificial light. This includes jewellery, tabletops, and decorative crafts—essentially, anything where unwanted yellowing would spoil your finish.
