Application of Lide Powder
- Nov 22, 2018 -

Lide powder (zinc bismuth white) pigment is widely used than zinc sulfide, and its structure is similar to that of zinc sulfide. It contains barium sulfate and has a slightly poor durability. The powdering resistance is poor. The price is cheap, so it can be used in place of titanium dioxide. Can be applied to all plastics, paints, coatings, thermoplastics, thermosets and paper, as well as the pigment industry, the cosmetics industry.


Lithopone (zinc bismuth)


Inorganic white pigment. Widely used as a white pigment for plastics, paints and inks such as polyolefins, vinyl resins, ABS resins, polystyrene, polycarbonate, nylon and polyoxymethylene.


Mainly used in latex paints, water-based paints, inks, rubber, plastics, etc., replacing 30% of rutile-type titanium dioxide in latex paints, still maintaining the original film properties, and has the effect of reducing costs.


Used as a white pigment, the 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. It is widely used in the paint industry to improve the durability of curing of zinc-white coatings and to prepare various color paints.


It is also used as a white pigment or filler in plastics and inks such as chloroprene sealant, nylon, polyolefin, vinyl resin, ABS resin, polycarbonate, polystyrene, polyoxymethylene, nylon, etc. Also used for coloring rubber, leather, paper, enamel, varnish, etc.


The characteristics and uses of three common types of Liede powder:


1, B301 lithopone: white pigment, zinc sulfide content of 28%. The hiding power is stronger than that of zinc oxide, which is worse than titanium dioxide and has good heat resistance.


     Main uses: paints, paints, inks, plastics, rubber, paper, enamel, etc.


2, B302 lithopone: white pigment, zinc sulfide content of 28%, after surface treatment has better dispersion than B301.


     Main uses: coatings, paints, inks, plastics, rubber, paper, etc.


3, B311 lithopone: white pigment, zinc sulfide content of 30%. It has stronger hiding power and achromatic power than B301, and has better dispersibility.


     Main uses: paints, paints, inks, plastics, rubber, paper, enamel, etc.
