Factory supply Cas 1345-05-7 Lithopone Pigment

Chemical Composition: Lithopone is mainly composed of barium sulfate (BaSO4) and zinc sulfide (ZnS), typically in varying proportions. The ratio of barium sulfate to zinc sulfide in lithopone can vary depending on the manufacturing process and the desired properties of the pigment.

Physical Properties: Lithopone is a fine white powder with good covering power and opacity. It has a high refractive index, which makes it useful as a pigment for producing white or tinted paints, coatings, plastics, and other materials.

Color and Uses: Lithopone is primarily used as a white pigment in various applications, including:

• Paints and Coatings: It is commonly used in the formulation of white paints, primers, and coatings due to its ability to provide opacity and brightness.
• Plastics: Lithopone is also used in the production of white or light-colored plastics to achieve desired coloration and opacity.
• Paper: It can be used in paper production to improve the brightness and opacity of paper products.
• Rubber: In the rubber industry, lithopone may be used as a filler or pigment in the production of white rubber products.
• Ink: Lithopone is sometimes incorporated into printing inks to achieve white or tinted colors in various printing applications.

Advantages: Lithopone offers several advantages as a white pigment, including its high covering power, brightness, and opacity. It is relatively inexpensive compared to other white pigments such as titanium dioxide, making it a cost-effective option for certain applications.

Regulation and Safety: Like other chemical substances used in industrial applications, the use of lithopone is subject to regulations and standards aimed at ensuring its safe handling, manufacturing, and use. Compliance with regulations regarding occupational safety, environmental protection, and product quality is important for manufacturers and users of lithopone.
