UV light can cause many epoxy resins to become yellow or cloudy over time, especially when projects are exposed to sunlight. Fortunately, specialist resins formulated for deep pours now contain strong UV filters that help preserve a crystal-clear finish for years.
Why Non-Yellowing Matters in Resin Casting
Yellowing is a common issue with standard resins as they age, particularly if the piece sits in sunlight. For deep pour projects like river tables, artwork or large castings made with silicone moulds, clarity and long-term stability are essential. Strong UV filters integrated into the resin help block out harmful rays, reducing discolouration to keep your project clear and attractive longer.
How UV Filters Work in High-Quality Epoxy Resins
Premium deep pour epoxy resins are engineered with advanced UV absorbers that inhibit light-induced chemical reactions inside the cured resin. For example, Epoxytable 10-Ten features strong UV filters, explicitly designed to guard against yellowing for up to 5 years. This type of formulation is crucial if you want resin surfaces to maintain their clarity wherever light exposure is likely.
When This Matters Most
If you’re creating tables, countertops or statement pieces with thick resin pours that will be near windows, in conservatories or other sunlit environments, investing in a resin with robust UV protection is particularly important. It’s also helpful for pieces meant to last and retain their beauty through years of daily use.
