Facebook← Back to Epoxy resin: tips for thick pours of two inches and beyond?
When working with epoxy resin in thick castings, exposure to sunlight can become a real challenge. Strong UV protection helps maintain clarity in your finished projects and keeps yellowing at bay, ensuring a long-lasting, attractive result.
How UV Protection Works in Epoxy Resin
Epoxy resins designed for deep pouring often include high-grade UV filters to minimise the risk of yellowing and maintain transparency. This is especially important for castings exposed to indirect or direct sunlight, where unprotected resin may degrade, develop yellow tints, or become brittle over time.
Premium deep pour epoxies, such as Epoxytable 10-Ten, guarantee strong UV resistance for several years, helping your pieces stay vibrant for longer. Always check if the resin specifies UV stability for thick casts rather than just thin coatings.
Choosing the Right UV-Resistant Resin for Your Project
If you intend to create river tables, large countertops or artistic blocks with significant thickness, select a resin formulated for both deep pours and robust UV protection. Standard craft epoxies may suffice for smaller, indoor pieces but can yellow quickly if exposed to daylight in thick sections.
- For pours up to 10cm, opt for a deep pour formula with proven UV filters.
- For castings up to 5cm, use products like EpoxyTable 5-Five for reliable stability and surface durability.
When this Matters Most
Strong UV protection is crucial if your finished resin project will sit near windows, under skylights, or in any area with regular light exposure. This is especially relevant for river tables, art installations, and countertops with clear or light pigments.
