Lithopone was discovered in the 1870s by DuPont. It was manufactured by Krebs Pigments and Chemical Company and other companies. The material came in different seals, which varied in the content of zinc sulfide. Gold seal and Bronze seals contain 40-50% zinc sulfide, offering more hiding power and strength. Although its popularity peaked around 1920, approximately 223,352 tons were produced in 1990. It is mainly used in paints, putty, and in plastics.
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. However, it is much cheaper than TiO2 and has advantages such as low binder requirement and good dispensability. As a white pigment, it can improve the substrate's weather resistance, and improve the fungicidal properties of paint formulations. Some of the major applications of Lithopone include manufacturing of paint pigments, plastic & rubber products, paper, printing inks, cosmetics, and leather & linoleum products. It is commercially available under names such as pigment white 5, Barium zinc sulfate sulfide, Becton White, C.I. 77115, Charlton White, Enamel White, and Zincolith. On the basis of content of ZnS, Lithopone is available at 28%-30% Lithopone and 60% Lithopone.
Because of its ability to absorb UV light, it's particularly useful as an ingredient in sunscreens — while its light-scattering properties are great for applications that require white opacity and brightness, such as in paint and paper.
- Moreover, anatase titanium dioxide contributes to the durability and longevity of coatings. Its excellent weatherability ensures that coatings remain intact and retain their performance properties even in harsh environmental conditions
anatase titanium dioxide in coatings manufacturers. This is crucial for outdoor coatings, which are exposed to a wide range of external factors that can degrade their quality over time. Does Titanium Dioxide Cause Cancer?
- Firstly, let's talk about the physical properties of titanium dioxide. It is a white powder that is insoluble in water and has a high refractive index, which makes it an excellent material for producing bright and opaque colors. Moreover, it is non-toxic, chemically stable, and resistant to discoloration from sunlight or heat. These characteristics make it ideal for use in various products where durability and safety are crucial factors.
To be added to food, this additive must achieve 99% purity. However, this leaves room for small amounts of potential contaminants like lead, arsenic, or mercury (1Trusted Source).
- In the world of industrial processing and manufacturing, the term 1250 mesh holds significant importance, particularly in the field of powder and particle size reduction. This refers to a screen or sieve with a very fine aperture, capable of separating particles down to an incredibly minute level. The demand for 1250 mesh products is driven by various industries such as pharmaceuticals, cosmetics, food processing, and mineral refining, among others, where ultra-fine particle sizes are essential for optimal performance.
- Titanium dioxide is a white powder that is commonly used as a pigment, opacifier, and UV blocker in various applications. When added to nitrile gloves, it can significantly improve their barrier properties, making them more resistant to chemicals and punctures. Additionally, TiO2 also provides excellent UV protection, which is essential in industries such as healthcare and cosmetics.
- The manufacturing process of emulsion latex paints involves combining polymer emulsions with pigments, additives, and water. Rutile TiO2 serves as the predominant pigment due to its superior light scattering abilities. Its small, uniform particle size ensures maximum surface area coverage, leading to a more vibrant and durable finish. Moreover, the rutile form exhibits good weather resistance and does not readily break down under exposure to UV light, ensuring that the paint maintains its color and integrity over extended periods.
- Despite its many benefits, there have been some concerns about the safety of TiO2 in food products. Some studies have suggested that TiO2 may have the potential to cause respiratory problems or other health issues in humans. However, these studies have been largely inconclusive, and the FDA has concluded that TiO2 is safe for use in food products at current levels of consumption.
- The construction industry, for instance, has long utilized cheap barium sulfate superfine as a filler in cement and concrete mixtures. Its high density contributes to increased weight and stability, while its inertness ensures minimal chemical reactions, enhancing the durability of structures. Moreover, in the oil and gas sector, it serves as a weighting agent in drilling fluids, preventing blowouts by adding density to the fluid and stabilizing wellbores.
- Titanium dioxide, on the other hand, is a white pigment that is commonly used in cosmetics and personal care products due to its excellent covering power and UV protection properties. In shampoo, titanium dioxide helps to neutralize yellow tones in hair, giving it a brighter and more youthful appearance. It also has antibacterial properties, which can help to reduce the risk of scalp infections and promote healthier hair growth.
