UV 329 is anexcellent photostabilizer of benzotriazole, widely used in polymers and other organic materials. It can absorb ultraviolet light of 270-340 nanometers, and has the characteristics of low volatile, non-coloring, extraction resistance and migration resistance. UV-329 is widely used in various optical materials because of its good transmittance in visible light. It can be used for packaging materials such as plastic container and food box, providing good light stabilization effect for them. Besides, it is especially suitable for light colored products.
APPLICATION
