Understanding Strong UV Filters in Resin

← Back to What causes resin?

When working with resin for tables, artwork, or crafts, maintaining a clear finish is crucial. Strong UV filters in epoxy resins give much-needed protection against discolouration and yellowing over time.

What Do Strong UV Filters Do?

Strong UV filters are additives included in quality epoxy resins to absorb ultraviolet light. This helps to shield the resin from the sun’s rays, one of the main causes of yellowing and colour shifts in resin projects. By intercepting these damaging UV rays, the resin retains its clarity and original appearance for much longer—even in well-lit spaces or outdoor situations.

Choosing a Resin with UV Protection

If your project is likely to be exposed to sunlight or bright indoor light, always check that the resin includes robust UV filters. For deep casts such as river tables or thick artistic pours, consider options like Epoxytable 10-Ten, which offers strong UV protection for up to 5 years. For thinner coats and crafts, a product like Icrystal can help maintain a glass-clear finish and resist yellowing.

When This Matters Most

• Furniture placed in conservatories, sunrooms or near windows
• Resin art intended for long-term display
• Any project where a crystal-clear result is essential over time
