PRODUCT INFORMATION
4000 mesh calcined kaolin is a calcined product of coal-measure kaolin, characterized by high whiteness, fine particles, porous surface and higher surface. Therefore, it has good dispersion and suspension in water-based or oil-based matrix, which can effectively prevent the deposition of the coating and give the coating a good canning effect.
This product is chemically inert, and does not react with acid at room temperature, so as to improve the weather resistance and scrub resistance of the coating.
