Lithopone Pigments Manufacturers An Overview of the Industry

Lithopone is a generic name for a white pigment composed of a mixture of zinc sulfide (ZnS) and barium sulfate (BaSO4). Invented in the late 19th century, lithopone serves as an important pigment for various applications due to its excellent opacity and durability. It is primarily used in paints, coatings, plastics, and paper, making it a crucial component in the manufacturing sector. In this article, we will explore the lithopone pigment market, key manufacturers, and the factors driving the demand for this versatile pigment.

Understanding Lithopone Pigments

Lithopone pigments are known for their brightness and lightfastness. With a high refractive index, it exhibits superior hiding power, which makes it ideal for use in products requiring a high degree of whiteness. The modern lithopone typically comprises around 30% to 60% zinc sulfide and is often combined with other additives to enhance its protective properties against ultraviolet (UV) light and chemical degradation.

The pigment is available in several grades, with the most common type being lithopone 28, which contains around 28% zinc sulfide. This specific grade is widely favored in the coating industry, owing to its excellent performance characteristics.
