What is calcined kaolin?
Whiteness: The whiteness of kaolin is divided into natural whiteness and calcined whiteness. The higher the calcined whiteness, the better the quality.
Product Introduction: Calcined kaolin is an aluminum silicate pigment and multifunctional additive made from high-quality kaolin using a special process. It has the characteristics of high whiteness, low impurity content, good light scattering performance, and easy dispersion.
In paper coating operations, it can replace titanium dioxide or other high-cost pigments, reduce production costs, improve the smoothness, opacity, and gloss of paper, and improve the ink absorption of paper.
In the coating industry, it can be used as a functional additive to provide good hiding properties and partially replace titanium dioxide. It can not only reduce the cost of coatings but also adjust the gloss of coatings and improve the mechanical properties of coatings. It can also improve the storage stability and crushability of the coating system, improve the mechanical properties of the coating such as moisture absorption resistance and impact resistance, and improve the resistance of pigments to floating and blooming.
