Properties: White powder
Uses: Lithopone is a white pigment composed of a mixture of
barium sulfate (68 - 70 %) and zinc sulfide (28 - 30%) with
trace amounts of zinc oxide. It is produced by
precipitation through filtering, heating and quenching
works. Lithopone has mostly been replaced by titanium
dioxide which is more durable, but it is much cheaper. It
is used as a base for lake pigment and used as a inert
pigment for paint, ink and cosmetics as well as in a large
range of applications in plastic industry. It is used as a
filler in paper, leather, and linoleum.
Packing: 25kg P.P. bag.
