Eversorb® UR210 is a high-performance liquid UV light stabilizer blend for UV-curable coatings. It prevents degradation caused by sunlight UV radiation without impacting the curing speed in most formulations. Suitable for both clear and pigmented UV-curable coating systems, it is recommended for use on metal, wood, and plastic materials.
