Product Description

Product Description

Lithopone

Lithopone is an exceptionally versatile high-opacity white pigment, expertly crafted from barium sulfate (BaSO4) and zinc sulfide (ZnS) in a precise 70:30 ratio. This economically savvy composite pigment delivers a balance of moderate brightness and superior hiding power, perfectly bridging the gap between zinc oxide and the high-end titanium dioxide. Its meticulously engineered chemically co-precipitated structure ensures a flawless, even particle distribution, making it the ideal choice for applications where extreme durability is not a necessity.
