As a cornerstone inorganic white pigment, Lithopone (Barium Zinc Sulfate, C.I. Pigment White 5) continues to solidify its position as the preferred choice for manufacturers worldwide seeking an optimal balance of performance, quality, and economic efficiency. With its unique composition and versatile properties, Chinese-produced Lithopone is meeting surging global demand across key industries, from architectural coatings to plastic masterbatches.
What is Lithopone?
Lithopone is a synthetic, white crystalline powder comprising a co-precipitated mixture of Zinc Sulfide (ZnS) and Barium Sulfate (BaSO₄), typically in a ratio of 28-30% ZnS to 70-72% BaSO₄.
Superior Properties for Industrial Excellence
Our premium-grade Lithopone stands out in the global market due to its exceptional characteristics:
Exceptional Whiteness & Hiding Power: Boasts a high whiteness index (≥95%) and excellent opacity, effectively covering substrates.
Cost Efficiency: Offers a 30-50% cost reduction compared to Titanium Dioxide (TiO₂) while delivering comparable performance in many interior and non-exterior applications.
Excellent Dispersibility: Easily integrates into water-based and solvent-based systems, ensuring smooth, consistent color development.
Chemical Stability: Resists alkalis and most chemicals, maintaining integrity in diverse formulations.
Low Oil Absorption: Optimizes formulation costs and improves the flow properties of paints and plastics.
Diverse Applications Across Key Sectors
Paints & Coatings: Ideal for interior emulsions, industrial primers, and corrosion-resistant coatings.
Plastics & Rubber: Perfect for PVC, PE, PP, and rubber products, providing coloration and reinforcement.
Inks & Paper: Delivers bright white tones for printing inks and paper filling.
Specialty Uses: Applied in leather, ceramics, and masterbatches, offering versatility for specialized industrial needs.
