Understanding Lithopone A Comprehensive Overview of the 28-30% Grade and Its Suppliers

Lithopone is a white inorganic pigment primarily composed of zinc sulfide (ZnS) and barium sulfate (BaSO4). It has gained popularity due to its excellent opacity, brightness, and resistance to weathering. This makes it an ideal choice for various applications, including paints, coatings, plastics, and rubber. In this article, we will explore the significance of the 28-30% grade of lithopone, its benefits, and insight into suppliers of this pigment, focusing specifically on B301 and B311 grades.

The Importance of Lithopone Grades

Lithopone pigment is categorized into several grades based on its composition and properties. The 28-30% lithopone grade signifies a specific concentration level of the active ingredients necessary to achieve optimal performance. This concentration is particularly noteworthy as it balances pigmentation efficiency with cost-effectiveness.

The properties of lithopone allow it to function effectively in numerous commercial applications. Its high refractive index aids in providing excellent coverage and whiteness, while the barium sulfate component contributes to its stability and prevents chalking. These attributes make the 28-30% lithopone particularly advantageous when it comes to formulation into paints and coatings, ensuring durability and aesthetic appeal.

Applications of 28-30% Lithopone

The applications of lithopone, especially in its 28-30% grade, are wide-ranging. The most common industries where this pigment is employed include

1. Paints and Coatings Lithopone serves as an essential component in white paints and coatings, enhancing brightness and opacity. It is particularly effective in exterior formulations, where durability under UV exposure and weather conditions is crucial.

2. Plastics The addition of lithopone in plastic products helps improve their aesthetic quality. It enhances brightness and can improve UV resistance, making it suitable for various outdoor applications.

3. Rubber Products Lithopone is utilized as a filler in rubber manufacturing, contributing to better processing and enhanced physical properties, such as elasticity and strength.

4. Cosmetics The non-toxic nature and opacity of lithopone make it suitable for use in cosmetic formulations, providing effective coverage in makeup products.

Finding Reliable Suppliers

When looking for suppliers of 28-30% lithopone, particularly grades B301 and B311, it is essential to consider a few factors. Firstly, the supplier’s credibility and production methods should be evaluated to ensure product quality meets industry standards. A reputable supplier will often provide certificates of analysis (COA) detailing the chemical composition and purity levels.

1. B301 Grade This grade is known for its excellent balance of bright whiteness and opacity. It is often used in premium paints and high-end plastic formulations. Suppliers of B301 grade lithopone typically focus on quality control and can provide detailed specifications about their products.

2. B311 Grade On the other hand, the B311 grade is recognized for its enhanced durability and lower oil absorption characteristics, making it suitable for outdoor applications. Suppliers offering B311 grade lithopone may also provide technical support regarding the incorporation of their product into formulations, ensuring optimal performance.

Conclusion

Lithopone, especially in its 28-30% grade, is a versatile inorganic pigment that offers numerous benefits across various industries. Its exceptional properties make it a go-to choice for manufacturers involved in producing paints, coatings, plastics, rubber, and even cosmetics. As you explore options for sourcing this essential material, focusing on reliable suppliers of B301 and B311 grades will ensure that your formulations achieve the desired quality and performance standards. Awareness of the key characteristics and applications of lithopone will help industries harness the full potential of this remarkable pigment.
