【Products】Fine calcined kaolin(6000-mesh)
 
【Product detail】

Yuanjiang Brand - fine calcined kaolinIs to choose the high quality kaolin with special process of aluminum silicate extender pigment and multifunctional additives, with high whiteness, low content of impurities, light scattering performance is good, easy to disperse characteristics.In paper coating operation, can replace titanium dioxide or other cost higher pigments, reduce production cost, improve the paper smoothness, opacity and gloss, improve the printing ink absorbency of paper.In the coating industry can be used as a functional additive, provide a good cover performance, partly replacing titanium white, can reduce the cost of paint, and is able to adjust the gloss of coating, to improve the mechanical properties of paint film, and can improve the storage stability, besmear brushs paint system, improve the absorption of moisture resistance and impact resistance of the coating such as mechanical performance, improve the color and hair flower pigment anti-uplift.
