Can Gel Epoxy Resin Resist Yellowing?

How UV Protection Affects Yellowing

Gel epoxy resins are vulnerable to ultraviolet (UV) light, which can gradually cause them to yellow or lose clarity. To address this, premium casting and coating resins, such as Art Pro Deluxe and One-2-One, incorporate specialised UV filters within their formulas. These filters act as a shield, greatly slowing the discolouring process to help maintain a clear appearance for years.

Choosing a Resin with Long-Lasting Clarity

When purchasing gel epoxy resin for applications like art, jewellery, or furniture finishes, always check for mention of UV resistance or filtering. Some resins provide a 10-year warranty on clarity, offering peace of mind for decorative items that need to stay bright over time. Avoid generic or low-grade epoxies if UV exposure is a concern, as they may not contain adequate protection to slow yellowing.

When This Matters Most

• Displayed items: Artworks, trays, or furniture in well-lit rooms benefit from resins with robust UV resistance.
• Jewellery and coasters: These often experience direct sunlight or heat, making a yellow-resistant resin highly recommended.
