Lithopone B311 Powder A Comprehensive Overview

Lithopone is a white pigment that has been widely used for over a century in various applications, including paints, coatings, plastics, and cosmetics. One of the most notable grades of lithopone is Lithopone B311, which stands out for its exceptional hiding power and durability. This article aims to provide an in-depth look at Lithopone B311 powder, including its composition, properties, applications, and various factories producing it.

Composition and Properties

Lithopone is a mixture of barium sulfate (BaSO4) and zinc sulfide (ZnS). Lithopone B311 typically contains approximately 30% to 35% zinc sulfide, and the percentages can vary slightly among manufacturers. This specific blend allows Lithopone B311 to exhibit unique characteristics compared to other pigments.

The primary properties of Lithopone B311 include

1. High Opacity Lithopone B311 offers excellent hiding power, which makes it a preferred choice in applications where color coverage is vital. Its ability to mask underlying colors effectively makes it ideal for use in paints and coatings.

2. Chemical Stability This pigment is resistant to weathering and UV radiation, providing long-lasting results without fading. These attributes ensure that products containing Lithopone B311 can maintain their aesthetic appeal over time.

3. Non-Toxic Lithopone B311 is considered safer than some other white pigments, such as lead carbonate and titanium dioxide, making it a more environmentally friendly option.

4. Fine Particle Size The powder is available in various particle sizes, allowing for customization based on application needs. Finer grades provide better dispersion and smoother finishes in latex paints and other formulations.

Applications

- Paints and Coatings Due to its excellent opacity and durability, Lithopone B311 is widely used in architectural paints, industrial coatings, and automotive paints. It helps achieve a brilliant white finish and enhances the overall aesthetic quality.

- Plastics It is often used in plastic manufacturing, particularly in PVC formulations, where the pigment contributes to brightness and prevents discoloration.

- Cosmetics Lithopone is popular in cosmetic formulations, such as foundations and powders, owing to its non-toxic nature and soft, white appearance.

- Paper and Textiles In the paper industry, Lithopone B311 is used to increase brightness and opacity, leading to higher-quality products. Similarly, it finds application in textiles as a colorant.
