Yuejiang Brand - Lithopone B301
Lithopone is a white crystalline powder, composed of a mixture of zinc sulfide (ZnS) and barium sulfate (BaSO₄). The more zinc sulfide it contains, the stronger the hiding power and the higher the quality of the product. Lithopone has a density of 4.136–4.34 g/cm³ and is insoluble in water.
Widely used in various medium-to-high-grade interior and exterior paints, latex paints for walls, industrial coatings, powder coatings, as well as in plastics, rubber, inks, leather, and paper-making industries.
