Product Description

Product Description

Lithopone

Lithopone is a premium high-opacity white pigment, expertly crafted from barium sulfate (BaSO4) and zinc sulfide (ZnS) in an optimal 70:30 ratio. This economical pigment is renowned for its moderate brightness and impressive hiding power, seamlessly bridging the gap between zinc oxide and the high-performance titanium dioxide. Its unique chemically co-precipitated structure guarantees a uniform particle distribution, making it the ideal choice for applications where extreme durability isn't a priority.
