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 Lithopone has mostly been replaced by titanium dioxide which is more durable, but it is much cheaper.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: 25kgs net bag, 21mts in the 20'FCL
