- Leveraging calcined kaolin uses in paint, this material acts as an excellent extender for titanium dioxide, offering cost savings and improved opacity and whiteness in formulations.
- Exploring the properties of calcined kaolin reveals its ability to enhance scrub resistance and durability in coatings, contributing to longer-lasting finishes.
- For the ceramics industry, calcined kaolin provides excellent whiteness and imparts mechanical strength and a fine white surface texture, crucial for high-quality products.
- As a titanium dioxide extender, calcined kaolin effectively prevents agglomeration of TiO2 particles, acting as an anti-settling agent and improving paint stability during storage.
Product Advantages
Enhanced Opacity and Whiteness
The calcination process significantly increases the whiteness and opacity of kaolin. This makes it an ideal pigment extender for titanium dioxide, allowing for formulations with reduced TiO2 content while maintaining or improving brightness and coverage.
Improved Durability and Resistance
Calcined kaolin particles are harder and sharper, which contributes to enhanced scrub resistance, abrasion resistance, and overall mechanical strength in coatings and polymer applications, ensuring greater product longevity.
Cost-Effective Formulation Optimization
By partially replacing expensive prime pigments like titanium dioxide, calcined kaolin offers significant cost reduction opportunities in paint and coating formulations without compromising quality, aligning with the goal of finding cost-effective titanium dioxide extension solutions.
Key Applications
Paints and Coatings
Calcined kaolin is widely used as an extender pigment, improving opacity, gloss, color, and viscosity, while reducing the need for expensive prime pigments.
Ceramics
In ceramics, it enhances whiteness, provides good dielectric strength, and imparts mechanical strength for products like tiles, insulators, and refractories.
Paper and Board Manufacturing
Used as a filler and coating, it improves paper appearance, brightness, opacity, and printability, and is key in deinking recycled paper.
Plastics and Rubber
It acts as a reinforcing filler, imparting tensile strength, fire resistance, and UV resistance to plastics and rubber compounds, especially in wire and cable insulation.
