Zinc sulfide white / white powder pigment Lithopone B301 & B311
1.Simple Introduction of B301/B311 Lithopone
The appearance of lithopone is white powder, relative density: 4.136 ~ 4.39 g/mL, insoluble in water. Lithopone is a mixture of zinc sulfide and barium sulfate. As an inorganic white pigment, it is widely used as a white pigment for plastics such as polyolefin, vinyl resin, ABS resin, polystyrene, polycarbonate, nylon, polyoxymethylene and other paints and inks. Lithopone is less effective in polyurethanes and amino resins, and less applicable in fluoroplastics. Lithopone is also used in the coloring of rubber products, paper, linoleum, linoleum, leather, watercolor paints, paper, enamel, and the like. Lithopone is used as a binder in the production of electric beads.

3.B301/B311 Lithopone Application
(1) Lithopone can be used in latex paints, water-based paints, inks, rubbers, and plastics. It replaces about 30% of rutile titanium dioxide in latex paints. It can still maintain the original coating performance and has the effect of reducing costs.
(2) Lithopone can be used as an inorganic white pigment. Widely used as polyolefin, vinyl resin, ABS resin, polystyrene, polycarbonate, nylon and polyoxymethylene and other plastics and paints, inks, white pigments.
(3) Lithopone can be used for the coloration of rubber products, linoleum, leather, paper, enamel, and the like.
(4) Lithopone can be used as a white pigment, hiding power is second only to titanium dioxide, but stronger than zinc oxide. The hiding power increases as the ZnS content increases, and the light resistance also improves, but the acid resistance decreases.
(5) Lithopone powder can be used in the paint industry to improve the durability of zinc white paints and to modulate various paints.
