Product Description

Product Description

Lithopone

Lithopone is a high-opacity white pigment composed of barium sulfate (BaSO4) and zinc sulfide (ZnS) in a typical ratio of 70:30. This cost-effective composite pigment offers moderate brightness and hiding power, bridging the gap between zinc oxide and premium titanium dioxide. Its chemically co-precipitated structure ensures uniform particle distribution, making it suitable for applications where extreme durability is not required.
