Application
1.As extension agent of titanium dioxide, calcined kaolin is applied in such fields as water-based paint, paint, putty, and sealant. On one hand, with good light scattering, it can provide good covering property, partially replacing expensive titanium dioxide, and reduce coating cost. On the other hand, with high whiteness, high dispersibility, and stronger chemical inertness, it can adjust coating's gloss, and improve coating system's storage stability, pigment's anti-floating color, and coating's weather resistance, acid resistance, and alkali resistance. In particular, it is essential to prepare low-VOC and high solid content coating
2. It replaces titanium dioxide partially and improves the usage result of titanium dioxide in paper coating applications and enhance the brightness, glossiness,smoothness, opacity and improve the ink absorption ability, printing adaptability and printing gloss of paper.General used in coated paper, art paper, coated manila, newspapers, thermal paper, etc
3.It is with advantages as high volume resistance, good compatibility with basic material, good dispersibility, high pureness, and strong chemical inertness, so that cable insulation materials'insulating property, mechanical property, processing rheological property, ageing-resistant performance
4.Using calcined kaolin as extension agent of titanium dioxide has become a frequently-used method for many systems. calcined kaolin is low in cost and excellent in performance (such as easy for color modulation, good dispersibility, good chemical stability, difficult of changing color), and easy for processing.
5.Used for improving air impermeability of rubber plug. because of chemical inertness of kaolin, rubber's ageing resistance and chemical stability can be enhanced effectively,meanwhile,it can enhance color and coating strengt
