Dragonsorb® 120 is a sterically hindered hydroxybenzoate UV absorber, which converts UV radiation into heat energy through reversible chemical rearrangement. When compared to benzotriazole UV absorbers, it can provide excellent initial color and has a synergistic effect with hindered amine light stabilizer. It can be used with a hindered phenol antioxidant, a phosphite antioxidant, and a hindered amine light stabilizer at the same time to improve the weatherability of outdoor products. It can also be used simultaneously with benzotriazole UV absorbers to improve the weatherability of products, such as TPO car bumpers. The recommended use level of this product in PP, PE, TPO, PVC, EVA, unsaturated polyester, and ABS is 0.20 - 1.0%.
