1. Calcium Carbonate (CaCO₃)

Functions: Main filler to reduce production cost; improves smoothness, whiteness, and dry film strength.

Types:

PCC (Precipitated Calcium Carbonate): Fine particles, good dispersion, suitable for high-end paints.

GCC (Ground Calcium Carbonate): Cost-effective, widely used in interior wall paints.

Nano Calcium Carbonate: Enhances opacity and film density.

2. Kaolin Clay

Functions: Improves suspension and anti-settling; increases wear resistance and film strength; enhances gloss.

Features: Fine particle size and high purity, improves coverage and smooth texture.

3. Wollastonite

Functions: Enhances hardness, wear resistance, weather resistance, and adhesion.

Applications: Industrial anti-corrosion coatings, powder coatings.

4. Barium Sulfate (BaSO₄)

Functions: Increases gloss, chemical resistance, and weather durability; offers certain transparency.

Applications: Automotive coatings, powder coatings, decorative paints.

5. Titanium Dioxide (TiO₂)

Functions: The most important white pigment; excellent opacity, brightness, and weather resistance.

Applications: Widely used in high-grade paints and coatings; a key component for performance.

6. Mica Powder

Functions: Improves crack resistance, flexibility, and durability; plate-like structure enhances barrier protection.

Applications: Exterior wall paints, anti-corrosion coatings.

7. Diatomite

Functions: Enhances absorption, wear resistance, and thixotropy; improves opacity and anti-settling.

Applications: Special functional coatings, eco-friendly interior paints.
