• In the paint and ink industry, high-purity Barium Sulfate is regarded as an indispensable functional filler, with its exceptional performance stemming from its unique physical and chemical properties. As a chemically inert substance, it does not react with other components in the paint system, ensuring formulation stability. Meanwhile, its high whiteness and refractive index effectively enhance the coating's opacity, meaning a thinner film can achieve perfect hiding, thereby saving on the usage of more expensive titanium dioxide. Furthermore, Barium Sulfate has a moderate Mohs hardness, and its particle structure is often meticulously engineered to be uniform cubes or spheres. This not only significantly improves the film's hardness, wear resistance, and scratch resistance but also enhances the product's leveling and prevents settling, resulting in a smoother final film surface. Whether for interior/exterior wall paints, industrial protective coatings, or automotive primers, high-purity Barium Sulfate provides excellent weatherability, acid resistance, and corrosion resistance in harsh environments. Our product undergoes strict grinding and classification processes, featuring extremely low impurity content and a concentrated particle size distribution. It meets the stringent requirements of high-end coatings for fineness, gloss, and stability, serving as a key additive to enhance the overall competitiveness of your paint products.
