calcined clay/ calcined kaolin HS-801A [Product name]HS-801A Ultra Fine & Super White Calcined Kaolin [Character and Performance] HS-801A calcined kaolin giving very high opacity, high whiteness, fine particle, good dispersion, little residue on 325 mesh sieve,Super whiteness, good light dispersion ,fluidity and chemical stability, dont react with other solvents, good floatability against sedimentation. HS-801A is a very effective opacifying extender in , partially replacing TiO2, reducing the overall cost of paint formulations but maintaining paint film quality.It can improve the properties of paints such as scrub resistance, abrasion endurance, ageing resistance and stability during storage. It is especially necessary in making the paints of low VOC and high solid content. It is similar to Satintone W. [Application] Widely used in high-quality paints such as emulsion paint, powder coating, oily paint, etc. [Physical specification]SpecificationHS-801AWhiteness (%)≥93.5Particle size(-2μm,%)80-84Residue on 325mesh (%)≤0.003Oil absorption (g/100g)55-65PH6.0-8.0Water content (%)≤1.0　　　　　　　　　　　　　　　Average particle size(μm)≤0.9Refractivity1.62Dispersion (μm)≤45
