  • Applications

    Brilliant Black BN is a synthetic black pigment used as a colorant in a range of industrial formulations. In coatings and printing inks, it provides a deep black hue and opacity. In plastics and polymers, it is incorporated into color concentrates and masterbatches for consumer and industrial products. In rubber and elastomer compounds, it serves as a pigment for tires, rubber components, and molded parts. It is also used in adhesives and sealants to achieve uniform coloration. Depending on regulatory requirements, it may be used in cosmetics and personal care formulations as a colorant.
