When working with translucent epoxy resin, maintaining that beautiful, crystal-clear finish is essential. UV resistance is a key factor in ensuring your projects stand the test of time, keeping them as vibrant as the day they were made.
How UV Light Affects Resin Clarity
Exposure to sunlight and artificial UV sources can cause epoxy resin to yellow or lose its original brilliance over time. While slight discolouration is natural with many clear materials, non-UV-resistant resins are particularly vulnerable, leading to faded or cloudy finishes in your art, jewellery, or furniture projects.
Choosing UV-Resistant Resin and Colourants
Opt for clear casting resins that include built-in UV filters. Products like “Trasparente” multipurpose epoxy resin and “Icrystal” clear epoxy resin both incorporate UV protection to keep castings clear and vivid. Pair these resins with compatible, high-quality colourants for the best effect, and always follow dosage guidelines for transparent shades. Storing finished pieces away from direct sunlight can further preserve their clarity.
When UV Resistance Matters Most
- Projects displayed in well-lit or outdoor settings
- Jewellery and art that require long-term clarity
- Functional items like tabletops or countertops that get regular use
