Calcined Clay - Anhydrous Aluminium Silicate | High Whiteness, Excellent Durability, Superior Paint & Rubber Reinforcement

Calcined Clay (Kaolin) is an anhydrous aluminium silicate produced by heating ultrafine natural kaolin to high temperatures in a kiln. The calcination process increases whiteness and hardness, improves electrical properties, and alters the size and shape of the kaolin particles.

Advantages

Cost Effective and TiO2 Extension

Gloss and Sheen Control

Rheology Control and Suspension

Environmentally Friendly

Excellent Durability, Weathering and Barrier Enhancement

Washability and Scrub Resistance

High Opacity and Tinting Strength


Application

Paint : Improves structural strength in both water- and oil-based paints. It offers good dispersion, chemical stability, corrosion resistance, fire resistance, scrubbing resistance, and mechanical characteristics. It can further improve the storage stability, brushability, moisture assistance, and impact resistance of paints and coatings.

Rubber: It has a significant reinforcing action, is an electrical insulator, and can improve tear resistance, tensile strength, aging resistance, and corrosion resistance. It can enhance solubility in latex, increase vulcanization hardness and abrasion resistance, and boost flex life and smoothness.

Glass : Calcined kaolin replace costly alumina. When used as a filler in white glass products, it can improve product quality and reduce production costs.

Plastic : Calcined kaolin can enhance the strength of greenhouse film, ground film, cable insulation, and PVC pipe (sheet). Apartfrom whiteness and electrical insulating properties, it also allows diffuse light transmission and blocks infrared when used in plastic film. It can reduce cost when used as a bulk filler.

Paper : The laminar structure of calcined kaolin makes it a useful coating pigment in papermaking. Apart from good covering ability and relatively high luster, calcined kaolin's porous structure can increase the porosity, soft bulk, and smoothness of coating layers. It lends opacity and flexibility to paper, improves ink adsorption, enhances luster, and reduces printing spots.
