UV light can cause resins and finishes to yellow over time, dulling the original clarity of your projects. Modern resins are often formulated with an integrated UV filter designed to help preserve that fresh, glass-like appearance for longer.
Why Use a UV Filter in Resin?
Direct sunlight and artificial light both emit UV rays, which can gradually change the look of uncured or unprotected resin. A UV filter in your resin helps slow this process, helping to maintain transparency and gloss in decorative coatings, art, and even repairs to car glass. When clear, long-lasting results matter, selecting a resin with UV protection becomes crucial.


Choosing a Resin with UV Protection
Not all resins offer the same level of defence against yellowing. Trusted options like “Icrystal” Epoxy Resin explicitly feature UV filters, designed for a non-yellowing finish with a 10-year anti-yellowing warranty. For projects requiring thicker pours or high clarity, “Trasparente” resin is another reliable choice, also providing UV shielding to protect your work over time.
When Does UV Protection Matter Most?
- Outdoor or Sunlit Locations: Items exposed to direct sunlight.
- Jewellery and Tableware: High-gloss finishes where discolouration affects appearance.
- Restoration or Car Glass Repairs: Surfaces where clarity is essential for safety and aesthetics.
