Calcined kaolin (special for coating)
Performance:Kaolin is a non-metallic mineral, which is a kind of clay and clay rock mainly composed of kaolinite clay minerals. Because it is white and delicate, also known as white earth.
Features:Due to the high purity of kaolinite, the content of harmful elements is very low, so not only the treatment process is simple, but also the whiteness of the product is high, the average whiteness can reach 93%, the highest whiteness can reach 97%, used in papermaking can improve the whiteness of coated paper, instead of some titanium dioxide, can reduce costs. The viscosity concentration is high, up to 74%, the dispersion is good, the covering rate is strong, and it has good compatibility with natural and synthetic adhesives and other additives in the formula, which can make the coating have good rheological properties, especially suitable for coating machine with high solid content. The abrasion value is low, the material is heated evenly, and local over-burning will never occur. The tested abrasion value is only 3.6mg/2000 times.
Scope of application:Suitable for high-grade paint, paint, ink, rubber, plastic, wire and cable, etc.
1. Papermaking, coating can replace some expensive titanium dioxide.
2. Paint, water-based latex coatings.
3. Rubber and special cable reinforcing agent, industrial plastic functional filler, ink, food, medicine, cosmetics filler.
4. Advanced porcelain and special ceramic raw materials.
