If you’re planning a coloured resin project that will be displayed outdoors or in direct sunlight, it’s essential to select the right epoxy system to ensure your work remains vibrant and clear over time.
Why UV Resistance Matters for Coloured Epoxy
Direct sunlight can cause standard epoxies to yellow or degrade, which not only dulls the clarity but also alters the colours of your resin art or fixtures. UV resistant and non-yellowing formulas provide a crucial shield for maintaining the brightness and fidelity of both transparent and pigmented finishes even after prolonged sun exposure.
Best Practices for Outdoor Resin Colours
For outdoor projects, opt for epoxy systems engineered with UV filters, such as ICreation or Trasparente. These resins offer clear, glossy finishes that resist yellowing and keep colours stable even in sunny conditions. When adding pigment, always use colourants formulated for compatibility with epoxy like the Colourfun range, to avoid disrupting the resin’s protective properties.
- Mix pigments thoroughly for even colour distribution.
- Follow manufacturer guidance on mixing ratios to retain UV resistance.
- Apply in thin coats where possible for best surface protection.
When This Matters Most
UV resistant epoxy is especially important for pieces such as outdoor art, decorative panels, garden furniture, or resin-coated surfaces exposed through windows. Failing to use the right resin can result in permanent colour shift, yellowing, or loss of gloss.
