Calcium carbonate is one of the most widely used mineral fillers in paints and coatings — improving whiteness, opacity, and surface smoothness. To ensure high-quality performance, the powder should meet the following standards 👇

✅ High Purity (CaCO₃ ≥ 98%) – Ensures brightness and color consistency

⚪ Fine Particle Size (D50: 2–10 µm) – Provides smooth surface and uniform film

💎 Low Impurities (Fe₂O₃, SiO₂, MgO) – Prevents discoloration and surface defects

✨ Good Dispersion & Compatibility – Blends easily with resins and pigments

🌿 Stable Whiteness & Low Oil Absorption – Improves gloss and reduces cost

Liming Heavy Industry provides advanced grinding solutions for ultra-fine calcium carbonate production — helping coating manufacturers achieve high brightness, strong hiding power, and perfect smoothness.
