Calcined Kaolin
Product description
HY-T-80 is a kind of calcined kaolin powder with lamellar structure. Its chemical composition is anhydrous aluminium silicate. The product has high whiteness, suitable particle size and reasonable particle size distribution, and is widely used in the field of coatings. The utility model has the advantages of low oil absorption, good extinction effect and good covering performance, and improves the cracking resistance, scrub resistance and salt fog resistance of the paint film. It is the best extension agent for expensive titanium dioxide, which can partly replace titanium dioxide and reduce the cost of filler. CAS 92704-41-1.
