About this product
Product information from the supplier.
Our High Whiteness Precipitated Barium Sulfate is a premium functional filler jointly developed by Fengersheng Mining and Kansai Paint Co., Ltd. of Japan. Specifically engineered for high-end coating and ink applications, this product combines exceptional purity with superior dispersibility, allowing manufacturers to significantly reduce the reliance on expensive titanium dioxide without compromising the final visual quality.
By utilizing an ultra-fine particle size and high refractive index, this precipitated barium sulfate enhances light reflectivity and surface smoothness. It is an indispensable additive for industrial surface treatments, automotive finishes, and decorative coatings, ensuring a vivid, professional finish while optimizing overall production costs through efficient material extension.
