Lithopone is a white pigment composed of a mixture of barium sulfate (*8 - *0%) and zinc sulfide (*8 - *0%) 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It is produced by precipitation through filtering, heating and quenching works.Lithopone has mostly been replaced by titanium dioxide which is more durable, but it is much cheaper.
Sum total of zinc (m/m): *9.0% min(based on zinc sulfate and barium sulfate)
Total zinc amount: *8% min (based on zinc sulfate)
Zinc oxide (m/m): 0.8% max
**5 C volatile substance (m/m): 0.3% max
Water soluble salts(m/m): 0.1% max
Residue on sieve (*3um sieve pore)(m/m): 0.1% max
Water extraction alkaline: neutral
Oil absorption (g/**0g): *4
Reducing color powder (compare with standard sample): **0%Covering powder (contrast ratio): not lower than 5% standard sample
