Understanding Lithopone B301 and B311 Variants in Industrial Applications

Lithopone, a white pigment composed of zinc sulfide and barium sulfate, has been widely utilized in various industries due to its excellent opacity, brightness, and durability. Among the different grades of lithopone, B301 and B311 are particularly notable for their unique properties and applications. This article aims to explore these variants, their manufacturing process, applications, and current market quotes relevant to manufacturers and consumers alike.

What is Lithopone?

Lithopone is a mixture of zinc sulfide and barium sulfate, typically available as a white powder. This pigment is known for its high thermal stability, non-toxicity, and excellent resistance to UV light, making it suitable for a wide range of applications, especially in paints, coatings, plastics, and paper industries.

Key Variants B301 and B311

1. Lithopone B301 Lithopone B301 is a highly refined version of lithopone characterized by its fine particle size and superior hiding power. It typically has a brightness level exceeding 90%, which significantly enhances the aesthetics of end products. Additionally, B301 is known for its excellent dispersion properties, making it an ideal choice for high-quality paints and coatings.

2. Lithopone B311 Lithopone B311 differs slightly from B301 in terms of composition and performance. It is formulated for applications requiring improved durability and resistance to environmental factors. B311 boasts superior opacity and is often preferred for outdoor coatings, automotive finishes, and industrial applications where longevity is crucial.

The production of lithopone involves a chemical reaction between barium sulfide and zinc sulfate, followed by washing, drying, and milling to achieve the desired particle size. Advanced manufacturing techniques ensure that impurities are minimized, resulting in high-quality pigments. Manufacturers often employ rigorous quality control measures to verify the dispersion, opacity, and brightness of the final product.

Market Demand and Quotes

The demand for lithopone, particularly the B301 and B311 variants, has been on the rise. Industries are increasingly turning to lithopone as a sustainable alternative to traditional white pigments, such as titanium dioxide, due to its lower environmental impact. As of now, market quotes for lithopone B301 and B311 vary based on geographic location, raw material prices, and purity levels.

On average, manufacturers can expect quotes in the range of $1,200 to $1,500 per metric ton for these variants. However, prices can fluctuate based on global supply chain factors, technological advancements in manufacturing, and changes in regulatory policies regarding pigment use.
