supper fine calcined kaolin for paint ,coat and papermaking,it is a ecnomic functional filler .

1.Name:HS-801A Ultra fine & supper white calcined kaolin

2.Character  and 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.
