Kaolin is extensively used in the paper and coatings industries due to its brightness, opacity, and smoothness. In paper production, it acts as a filler and coating pigment, enhancing the paper's gloss, smoothness, and printability. In paints and coatings, kaolin improves opacity and reduces cost by acting as an extender, allowing for less use of expensive pigments. Its ability to provide a smooth, uniform surface also contributes to better durability and water resistance in coatings, making it suitable for interior and exterior paints.
HA-90T is a high brightness, fine particle size, reasonable particle size distribution and small screen residue calcined kaolin. It has low conductivity, low impurity content, low grind fineness, good dispersion stability, good suspension property and chemical stability. It can improve the sedimentary stability and longer service life of the electrocoat bath in electrophoretic paint. It also can improve salt spray resistance, smoothness, compactness and homogeneity of the film.
