Calcined Kaolin Clay
1. It's produced with ultrafine grinding then high-tempreture calcined modified By introduced advanced equipments oversea.
2. It has many superior properties such as plasticity, cohesiveness, dispersity, insulativity, sinterability, Fire resistance, refractoriness, absorbability, weather resisitance, stable chemical property,
3. High light scattered power and good hiding power etc.
4. Widely used in lines of paints, printing ink, coatings, plastics, rubber, glass, electrical string And lines, powder paint, road marks etc.
