Chemical composition
calcined kaolin:
Our calcined kaolin is a fully calcined aluminosilicate, and is superior in both color and other physical properties.
Calcined kaolin clay is chemically inert, has high covering power, provides desirable flow properties and reduces the quantity of expensive pigments required. Calcined kaolin clay is used as a functional TiO2 extender in paints, coatings and rubber.

Washed Kaolin:
Washed (Hydrous) kaolin is the feedstock for the calcined kaolin; water is still present in the crystal lattice structure.
Our washed kaolin is a low brightness material, and is widely accepted as a coating clay in ceramics and glazes, thanks to its excellent opacity and hiding power. It also serves as an extender in coatings, and as a hard clay in rubber systems.
