B301 White paint, 28% of the content of zinc sulfide, better hiding powder than zinc oxide, insoluble to water, no hydrogen sulfide and alkaline fluid, dissolving in acid into a hydrogen sulfide, worse hiding powder than titanium pigment, good heat resisting property.It is well-used in paint-making, printing ink, plastics, enamel, paper, oil cloth, leather, PVC and so on.
B311 White paint, 28% of the content of zinc sulfide, better hiding powder than zinc oxide, reducing powder and dispensability than B301.Same as B301
