Lithopone The Versatile White Powder Pigment and Its Suppliers

Lithopone is a white powder pigment primarily composed of zinc sulfide and barium sulfate. Known for its excellent opacity, brightness, and low cost, lithopone has been a staple in various industries since its introduction in the late 19th century. Its applications are diverse, ranging from paints and coatings to plastics, rubber, and even cosmetics. This article explores the characteristics of lithopone, its uses, and the suppliers who provide this essential pigment to different sectors.

Characteristics of Lithopone

Lithopone is primarily used for its opacity and ability to reflect light. It possesses excellent weather resistance, making it suitable for outdoor applications. The pigment is non-toxic, which is a significant advantage over traditional white pigments like lead and titanium dioxide. Lithopone offers a high degree of brightness, which contributes to its popularity in the manufacturing of paints and coatings. Additionally, it has good mixing properties with other materials, enhancing the overall quality and finish of the products it is used in.

There are different grades of lithopone, each suited for specific applications. For instance, lithopone grades can vary in terms of particle size and the proportion of the zinc sulfide to barium sulfate, allowing manufacturers to choose a product that meets their specific needs.
