Snowhite 90 is produced through strict control of process at about 1000 ℃ calcination. In the calcining process, kaolin lost its crystal water and its material morphology changed. The changes in its microscopic shape and surface chemical properties have endowed the product with a series of important properties that serve the paper industry. As a calcined kaolin pigment, it has the advantages of high whiteness, good light scattering performance, fine particles and low abrasion. It can be used as filler and coatings.

    Advantages
    • Reduce or avoid use of titanium dioxide in the formula to reduce the cost without reducing the main performance.
    • Improve paper smoothness, gloss and hiding power.
    • Improve ink absorption and overall printing performance.
    • It has the best viscosity and good compatibility with various preparations.
    • Low abrasion value can effectively reduce the frequency of scraper replacement and thus reduce the cost.
