caocined kaolin

1.Name:HS-801A Ultra fine & supper white calcined kaolin 2.Characterand performance: Very fine particle with distribution in narrow range, and little residue on 325 mesh; Super whiteness, good light dispersion and high covering power; Great dispersibility, fluidity and chemical stability, dont react with other solvents; Good floatability against sedimentation, used as an extender of titanium dioxide. It can improve the properties of paints such as scrub endurance, abrasion endurance, ageing resistance and stability during storage. It is especially necessary in making the paints of low VOC and high solid content.3.physical specification:SpecificationHS-801AWhiteness (ISO457 ,%)≥93.5Granularity (-2μm,%)80-84Residue on 325mesh (%)≤0.003Oil absorbency (g/100g)55-65PH6.0-8.0Water content (%)≤1.0Average particle size(μm)≤0.9Refractivity1.62Dispersibility (μm)≤45
