Paint Grade 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, don't react with other solvents, good floatability against sedimentation. HS-801A is a very effective opacifying extender in paint, 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.
