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.

Lithopone B301/B311(30%)
Lithopone B311(30%) 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-resisitance and is insoluble in water.
White powder, is a mixture of zinc sulfide and barium sulfate. Have high whiteness and good covering power. It is called Inorganic
white pigment. Widely used as white pigment of plastics such as polyolefin, vinyl resin, ABS resin, polystyrene, polycarbonate,
nylon and polyoxymethylene (POM), also for paint,ink ,grinding wheel and plaster. It is use to colourate for rubber products ,
linoleum, leather, paper, enamel.
Purposes: a pigment, mainly for the paint industry, paint and plastic industry, on the role of the color.
Packaging and packing: 25 g/PPG amount; In theory can be installed at 25 tons, but accounting price according to 20 tons of business accounting.
Characteristics: the cheap in white raw material, the price lower than too white powder.
