Exploring Lithopone A Look at Suppliers and Applications

Lithopone is a versatile white pigment composed of zinc sulfide and barium sulfate. It has been widely used in various applications, such as paints, coatings, plastics, and rubber due to its excellent covering power, durability, and non-toxic nature. As an alternative to titanium dioxide, lithopone offers a cost-effective solution while providing similar levels of opacity and brightness. This article will explore the key suppliers of lithopone, particularly focusing on grades like Lithopone 28, B301, and B311, and how they serve various industries.

Grade Overview

Lithopone grades are differentiated based on their chemical composition and intended use.

- Lithopone 28 This grade contains around 28% zinc sulfide and exhibits remarkable whiteness and outstanding stability in both oil and water. It's primarily employed in the manufacturing of paints and coatings, where brightness and opacity are crucial. Lithopone 28 plays a significant role in enhancing the aesthetic quality of end products.

- B301 Known for its excellent dispersibility, B301 offers superior performance in hydraulic applications, making it a favorable option for water-based paints and coatings. Its fine particle size contributes to its high covering power and is often sought after in construction materials, particularly in finishing mortars and compounds.

- B311 This grade is notable for its high resistance to weathering and UV degradation. B311 is particularly favored in outdoor applications where durability is a priority, such as exterior paints, thus retaining gloss and color over extended periods in harsh environmental conditions.
