Lithopone-Barium zinc sulfide
Identification:
Chemical Name: Barium zinc sulfide
Synonym: Barium zinc sulfate; Pigment White 5; C.I. 77115
CAS No.: 1345-05-7
Molecular Formula: Zn2BaS2O5
Lithopone is a white powder form pigment,produced by ZnSO4 and BaS, has good hiding power, excellent thermal stability. It can take place of expensive titanium dioxide to greatly cut the cost of production.
Lithopone is widely used in coating, printing ink,rubber and plastics field and so on.
