Optical Whitening Agent (OB) is a high-performance optical whitening additive used in the plastics and paint industries to increase the whiteness of products and provide a more vibrant appearance. It absorbs ultraviolet (UV) rays and re-emits them as visible blue light, thus achieving a brighter, cleaner, and more aesthetically pleasing whiteness in plastics, paints, and coating systems. Thanks to its powder form, it disperses easily and provides homogeneous distribution in production processes. When used in combination with titanium dioxide (TiO₂), it further enhances whiteness performance, offering higher optical quality and color vibrancy. Its high efficiency and wide range of applications make it a reliable choice in industrial production.
