Lithopone, an important inorganic pigment, is composed of a mixture of zinc sulfide (ZnS) and barium sulfate (BaSO4). Among its various grades, B301 and B311 stand out for their unique properties and applications across industries. Drawing on years of expertise and a track record of reliability, this article delves into the nuances that make these pigments advantageous for manufacturers worldwide.

The lithopone B301 grade is hailed for its excellent opacity, enhancing the hiding power of paints and coatings. With its superior whiteness, this grade is often utilized in environments demanding high aesthetic standards, such as interior paints and decorative finishes. Its ability to disperse easily without extensive milling provides a practical advantage for manufacturers focused on efficiency and product uniformity. This efficiency not only reduces production time but also enhances the pigment's performance in terms of coverage and finish, ensuring that the end products meet both regulatory and consumer expectations. In comparison, lithopone B311 offers a balanced profile of properties that cater to more demanding industrial applications. Recognized for its high weather resistance and stability, B311 is a preferred choice for exterior paints that require long-lasting durability against environmental elements like sunlight and rain. This grade combines the refractive benefits of ZnS with the inertness of BaSO4, resulting in a pigment that maintains its integrity over time, even in harsh conditions. These characteristics are backed by rigorous testing and industry certifications, establishing B311 as a trustworthy option for businesses in the construction and automotive sectors.

Both B301 and B311 grades serve as reliable alternatives to titanium dioxide, offering cost-effectiveness without compromising quality. With the mounting pressure on the raw material supply chain for TiO2, lithopone emerges as a viable solution, aiding industries in maintaining production standards and cost controls. The strategic use of these pigments can significantly optimize formulation costs, allowing manufacturers to achieve better pricing strategies while still adhering to international quality norms.lithopone b301 b311 zns.baso4
