Kaolin can undergo various processing methods to enhance its properties for specific applications. Processes such as calcination, bleaching, and particle-size reduction modify kaolin's color, brightness, and reactivity. Calcination involves heating kaolin to produce metakaolin, which has improved strength and reactivity, especially in construction and environmental applications. Bleaching removes impurities and enhances whiteness, which is essential for kaolin used in ceramics and paper. Different particle-size reduction techniques provide kaolin in diverse grades suited for unique industrial needs, from coarse fillers to fine pigments.
Britex-1000 is a kind of metakaolin calcined with fine temperature control. It has developed porosity, high oil absorption, concentrated particle size distribution and good dispersion, which can significantly improve the coating coverage. It is mainly used in the field of high-end coatings. It can improve the storage stability and coloring effect of the coating surface, replace titanium dioxide in large quantity, reduce the use cost of fillers and improve the gloss of the coating.
