Product Description
Calcined Kaolin High Brightness TiO2 Extender Pigment
Product Overview

Calcined Kaolin (CAS 92704-41-1), also referred to as calcined clay, is a high-performance industrial mineral produced through the controlled thermal treatment of beneficiated hydrous kaolin. Engineered for maximum brightness and optimized particle size distribution, it functions as a premium TiO2 extender and multifunctional filler in paints, coatings, paper, plastics, and rubber.

Its unique lamellar particle shape, excellent opacity, and superior dispersibility allow formulators to reduce costs while maintaining or improving optical and mechanical performance.

Key Features
  • High Brightness and Whiteness: Consistently achieves GE brightness values above 90%, significantly enhancing base color and enabling brilliant white and clean pastel formulations.
  • Exceptional Hiding Power: The engineered particle size and plate-like morphology maximize light scattering, providing true extension of titanium dioxide and reducing overall formulation cost without sacrificing opacity.
  • Superior Dispersibility: Controlled surface treatment and tight particle sizing promote rapid wet-out and uniform distribution in both aqueous and solvent-borne systems, minimizing grind time and energy consumption.
  • Chemical Inertness and Low Abrasion: Free from heavy metals and reactive impurities, it ensures long-term stability, predictable viscosity behavior, and minimal wear on processing equipment.
  • Consistent Batch Quality: Manufactured under strict process controls to guarantee narrow particle size distribution, consistent oil absorption, and reproducible rheological performance batch after batch.
Main Functions and Applications
Paints and Coatings

Calcined kaolin is primarily used as a TiO2 extender and opacifying agent in architectural, industrial, and powder coatings. It enhances dry hiding power, improves scrub resistance, and contributes to film integrity. Its fine particle size and low soluble salt content also help control gloss and sheen uniformity in flat, eggshell, and semi-gloss paints.

Paper and Paperboard

In the paper industry, calcined kaolin boosts brightness, opacity, and printability. It improves ink receptivity and reduces show-through in lightweight coated papers, newsprint, and packaging boards, enabling papermakers to achieve premium optical properties at a reduced basis weight.

Plastics, Rubber, and Elastomers

As a reinforcing filler, it increases stiffness, dimensional stability, and impact resistance in thermoplastics and thermoset composites. Its low abrasiveness protects molds and extruders, while its consistent color contribution supports bright white and clean tinted masterbatches and profiles.

Adhesives, Sealants, and Other Applications

Calcined kaolin also finds use in ceramic bodies and glazes for improved fired whiteness, in adhesives and sealants for rheology control, and as a functional filler in printing inks and water-based systems where consistent particle geometry is critical.
