Kaolin (China clay) is a premium mineral widely used in paints and coatings — improving coverage, adhesion, and smoothness. To ensure high performance and stability, kaolin powder should meet the following standards 👇

✅ High Purity (Al₂O₃ ≥ 35%) – Ensures color brightness and stability

⚪ Fine Particle Size (D50: 1–5 µm) – Provides excellent film smoothness and opacity

💎 Low Impurities (Fe₂O₃, TiO₂) – Prevents discoloration and improves whiteness

✨ Good Dispersion & Chemical Stability – Enhances uniform mixing and long-term performance

🌿 Moderate Oil Absorption – Balances gloss, viscosity, and cost efficiency

Liming Heavy Industry provides advanced grinding and classification solutions for ultra-fine kaolin powder — helping coating manufacturers achieve bright color, smooth texture, and durable coating quality.
