Washed Kaolin is produced by mixing raw kaolin with water to form a slurry, which then undergoes sedimentation for purification and is finally dried. This process yields a refined mineral that retains the essential properties of kaolin. It is characterized by its whiteness, cost-effectiveness, good fluidity, stable chemical properties, and a large surface cation exchange capacity. As a high-performance filler, it is extensively used in coatings and paints. It is also a key material in the manufacturing of firebricks, alumina-silica fiber, as well as in cosmetics and pharmaceutical products.
Light calcium carbonate usually appears in spindle or needle-like shapes with a narrow particle size distribution. It features uniform particles, high whiteness, large sedimentation volume, low oil absorption value, good dispersibility, and high chemical purity. These properties enable it to be widely used in numerous industrial fields, such as plastics, rubber, papermaking, and coatings.
Engineered as high-performance flaky glass fillers, glass flakes deliver enhanced anti-corrosion, wear resistance and barrier properties. Typically 2–10μm thick and 100–3000μm in diameter, they create a "labyrinth effect" in coatings/linings to block corrosive media penetration and extend the service life of industrial equipment and structures.
