Lithopone
1.CAS No.:1345-05-7
2.Properties:
Lithopone is a white pigment composed of a mixture of barium sulfate (28 - 30) and zinc sulfide (68 - 70%) with trace amounts of zinc oxide.
Lithopone, also known as Zinc barium white, non-toxic white powder, insoluble in water, and the role of acid decomposition emit hydrogen sulfide, and hydrogen sulfide and alkali does not work.It is a good heat resistance can be improved weather resistance,anti-algae,lower costs,and has excellent shielding power of whiteness.Its technical indicators are as follows
3.Uses:
Lithopone mainly an increase in whiteness , to improve weather resistance and so on. Is widely used in coatings, paints,inks,pigments,also used in enamel,plastic,paper,leather and so on, can replace some of the expensive titanium dioxide.
4.Applications:
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 Lithopone has mostly been replaced by titanium dioxide which is more durable, but it is much cheaper.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.
