We use high quality raw materials from Shanxi to produce calcined Kaolin. Our calcined Kaolin has high whiteness, ultra fine particle size, huge specific surface area, cellular surface, flake form, and then it has good dispersibility, excellent hiding power, super suspension properties. It can prevent sedimentation of coatings and improve weather resistance, scrub resistance and abrasion resistance of coatings.
