Product Description

Product Description

Lithopone

Lithopone is a sophisticated, high-opacity white pigment, expertly crafted from barium sulfate (BaSO4) and zinc sulfide (ZnS) in a precisely balanced ratio of 70:30. This cost-effective composite pigment offers a harmonious blend of moderate brightness and exceptional hiding power, skillfully bridging the gap between zinc oxide and premium titanium dioxide. Its unique chemically co-precipitated structure ensures flawless particle distribution, making it ideal for applications where extreme durability isn't paramount.
