TiO2 extenderElectrophoretic coatingWire & cable
Superfine Calcined Kaolin
Dehydroxylated Anhydrous Aluminum Silicate with High Whiteness, Opacity, and Electrical Insulation. An active extender that reduces titanium dioxide dosage while maintaining hiding power — widely used in paints, electrophoretic coatings, and wire & cable sheathing.
Key Technical Highlights
- Whiteness: ≥ 90% (ISO 2470)
- Anhydrous Al2O3: 42 – 46% (fully calcined)
- Loss on Ignition: ≤ 0.5%
- Fine Particle: D50 ≤ 2 μm (1250–5000 mesh)
