1. CAS No: 8006-32-4
2. Usage: Lithopone can replace titanium dioxide which is more durable, and 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.
3. Lithopone B310, Lithopone B302 and Lithopone B311
