Paint grade calcined kaolin

Descripción del producto

Character and Performance]： Very fine particle with distribution in narrow range, and little residue on **5 mesh; Super whiteness, good light dispersion and high covering power; Great dispersibility, fluidity and chemical stability, don’t 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. [Application]： Widely used in high-quality paints such as latex paint, powder coating, oily paint, etc. [Physical specification]： Specification HS***1A Whiteness (%) ≥*3.5 Granularity (*2μm，%) ****4 Residue on **5mesh (%) ≤0.**3 Oil absorbency (g/**0g) ****5 PH 6.**8.0 Water content (%) ≤1.0 Average particle size(μm) ≤0.9 Refractivity 1.*2 Dispersibility (μm) ≤*5 [Chemical specification]： SiO2（%）*2±2 Al2O3（%）*5±2 Fe2O3（%）≤0.5 TiO2（%）≤0.8 CaO（%）＜0.5 MgO（%）＜0.3 K2O（%）＜0.1 NaO（%）＜0.2 MnO（%）＜0.**4
