Introduction to Lithopone

Lithopone is the re-discovered white pigment with functional properties suitable for several applications. Lithopone is chemically inert and practically insoluble in acids, alkalis and solvents. Lithopone has therefore traditionally been used in stoppers and putties, jointing compounds and sealing compounds, primers and undercoats and in road-marking paints.

Functions of Lithopone

01/

Economic affordable
Compared with other white pigments such as titanium dioxide, Lithopone is more economical. With the effect of the same cover and color, the cost of Lithopone is lower, bringing you more affordable choices.

02/

Long -lasting weather, anti -ultraviolet rays
Lithopone's excellent anti -ultraviolet performance enables it to resist the color fades and deterioration caused by sunlight irradiation, ensuring lasting beauty in outdoor applications. Whether it is wind and rain or scorching sun, Lithopone can maintain colorful and bright colors.

03/

Excellent covering power
Lithopone has excellent covering power, and even under lower additions, it can effectively cover the underlying substrates, giving paint, coatings and plastic products the bright and non -transparent color effects.

04/

Good chemical stability is good
Lithopone's excellent chemical stability enables it to withstand various harsh environments, including acid -alkali, salt and fog and chemical erosion. Even under harsh environmental conditions, Lithopone can maintain stability of performance and ensure that the product is durable.

Usage of Lithopone

Plastic and polymers
Lithopone can effectively enhance the whiteness and opacity of plastic products, making its appearance more white and beautiful.
Lithopone's excellent ultraviolet absorption capacity can protect plastic products from degradation and aging caused by ultraviolet exposure, extending its service life.

Printing ink
Lithopone's excellent covering power can ensure that the ink spreads evenly on various substrate materials, and presents bright and full colors.
Lithopone's good liquidity and decentralization can make the ink print clear and sharp, and it is not easy to appear a paste and powder.

Ceramics and tiles
Lithopone can give ceramic glaze, tiles and sanitary ware higher brightness and smoothness, making its surface smoother, delicate, and better texture.
Lithopone's good decentralization can ensure that ceramic glaze is uniformly color, and flaws such as color spots are avoided.

Paint and paint
Lithopone's excellent covering power can effectively cover the bottom surface, reduce the amount of coatings, and give the paint surface higher brightness and gloss to enhance the decorative effect.
Lithopone's good chemical stability and weather resistance can improve the water resistance, acid and alkali resistance and ultraviolet rays of coatings, and extend the life of the coating.

Rubber products
Lithopone can significantly improve the stretch strength, hardness and abrasion resistance of rubber products, making it more durable and torn.
Lithopone's good weather resistance can enhance the resistance of rubber products to environmental factors such as wind, rain, ozone, and extending its service life.

Stability of Lithopone

From a stability standpoint, lithopone, a fusion of zinc sulfide and artificially precipitated barite, is non-toxic and exhibits resilience to mild lyes and acids. However, it is incompatible with colors containing copper. Despite its strong covering power in oil, lithopone's drying capabilities are notably limited, posing potential issues for artists.

Notably, early experimentation with lithopone-based grounds instead of zinc white resulted in undesirable darkening, although this blackness receded upon drying. Lithopone remains a subject of historical significance and contemporary relevance. While its applications and popularity have evolved, its role in the annals of pigment history is indisputable.

FAQ

Q: What is lithopone used as a white pigment is a mixture of?

A: Lithopone, C.I. Pigment White 5, is a combination of inorganic compounds and is commonly used as a white pigment powder. It is made up of a mixture of barium sulfate and zinc sulfide. Such insoluble compounds ideally blend with organic compounds and give opacity.

Q: How is lithopone obtained?

A: When barium sulfide and zinc sulfate are mixed, they undergo a double decomposition reaction to form lithopone, which is a mixture of barium sulfate and zinc sulfide. The lithopone product is further processed through filtering, drying, grinding and heating to produce the final pigment powder.

Q: Is lithopone toxic?

A: Lithopone is a white pigment made from a blend of zinc sulfide (ZnS) and barium sulfate (BaSO₄). It was developed in the 19th century as a safer alternative to toxic lead-based pigments, providing opacity and brightness in paints and coatings.

Q: What is the refractive index of lithopone?

A: LITHOPONE 30% L pigment has a refractive index of 1.86, high brightness and neutral hue. Low absorption in the near UV range helps increase compatibility with optical brighteners than other inorganic white pigments.

Q: How to use lithopone powder?

A: Lithopone White pigment is in powder. For use in artistic paint, it should be finely ground in a mortar before mixing it with the binder. Linseed oil : dilute the powder in some turpentine oil before adding it to linseed oil.

Q: What is the color of lithopone?

A: Lithopone is a white pigment, a mixture of barium sulfate and zinc sulfide.

Q: What is lithopone and titanium dioxide used as in paints?

A: Lithopone is an inorganic white pigment, obtained from co-precipitation of Zinc sulfide (ZnS) and Barium sulfate (BaSO4). Titanium Dioxide (TiO2) has replaced Lithopone as a white pigment in majority applications as TiO2 is more durable.

Q: What are the properties of lithopone?

A: Lithopone is an organically coated white pigment based on a co‑precipitated compound of zinc sulfide/barium sulfate. It is a transparent white almost equal to zinc oxide in whiteness and holds a medium position in density between lead white and zinc white.
