high white B301 lithopone white pigment � belongs to the in� general � use lithopone, the appearance is white power. it's characture is non-toxic, tasteless, not dissolve in water. chemical stalility and resistence to alkali.
Lithopone is a white, inorganic pigment composed of a mixture of barium sulfate (BaSO4) and zinc sulfide (ZnS). It is widely used in the production of paints, coatings, and printing inks due to its exceptional opacity and brightness. Lithopone enhances the covering power of these products, making it especially valuable in applications where whiteness and opacity are critical, such as in the manufacturing of high-quality paints and paper. It also contributes to corrosion resistance and durability in coatings. Despite its historical use, its production has declined in recent years due to environmental concerns related to the presence of barium compounds, with many industries opting for alternative white pigments like titanium dioxide. Nonetheless, lithopone's unique properties continue to make it relevant in certain niche applications within the paint and coatings industry.

Bt-in600 is a kind of lithopone whose hiding power is better than that of zinc oxide and worse than that of titanium dioxide. It has good heat-resistance and is insoluble in water. It does not react with sulfured hydrogen and bases. It will decompose and produce sulfured hydrogen consequently when comes across acids. Its color will change after solarization for a long time but can return to its original color in dark place. It is a kind of important material in coatings, paints, rubbers, printing inks, paper, porcelain enamel, leathers and plastics.
