The Importance of UV Resistance in Resin Projects

How Does UV Light Affect Resin?

Ultraviolet (UV) rays from the sun can break down the chemical bonds in many resins. Over time, this leads to yellowing and a loss of clarity, making once-vivid projects appear faded or dull. For clear resin projects or pieces requiring a high-gloss finish, these changes can be particularly noticeable and disappointing.

Choosing UV-Resistant Resins

To ensure your creations stay bright and crisp, look for resins specifically formulated with UV filters or additives. Products such as “Icrystal” Clear Epoxy Resin are designed to reduce yellowing, making them a solid option for projects like jewellery, furniture, or outdoor artwork. For larger pours and tables, consider a deep pour resin like EpoxyTable 5-Five, which also includes UV protection.

When UV Resistance Really Matters

• Outdoor tables, benches, and garden décor
• Jewellery and castings kept on sunny windowsills
• Any piece where long-term clarity is important

If your creation will sit in direct sunlight for extended periods, UV resistance goes from a nice-to-have to a genuine necessity.
