How to Prevent Yellowing and Surface Damage in Clear Resin

Yellowing and surface damage are common concerns when working with clear resin, especially for pieces meant to stay crystal clear over years of use. With the right choices and care, you can keep your projects looking their best for longer.

Choose UV-Resistant Epoxy Formulas

The most effective way to guard against yellowing is to select a resin with integrated UV filters. Products such as Icrystal and Trasparente are formulated to offer robust defence against discolouration from sunlight and environmental exposure. For furniture, decorative surfaces, and artwork, using a UV-stabilised resin is especially important for maintaining long-term clarity.
