AI Overview
Yellowish, solid particle polyester resin often results from UV light exposure, thermal degradation, or oxidation during storage, particularly due to the presence of benzene rings in unsaturated formulations. These particles, or "yellowing," can be caused by improper storage (oxygen exposure), overheating, or poor-quality, non-UV-stabilized resins.

Is resin still good if it turns yellow?
Yes, you can still use yellowed resin in many cases. It is often safe to work with, but it may not look good for clear or light colored projects. Instead, use it for darker pours, tinted pieces, or projects where the yellow will not show. This way, you do not waste your materials.Sep 29, 2025
