1.Calcined kaolin have high whiteness, the average whiteness is 93 %, the best whiteness can reach 97%. Use in paper-making can increase whiteness of coated paper, partial substitute the titanium powder, can reduce costs.
2. High viscosity, up to 74%, good dispersibility, possesses good compatibility with natural and synthetic adhesives or other additives in the formula, it can make the paint with good rheological properties.
3. Low abrasion loss, material is heated evenly , will not lead to partial over-burning, According to tests ,the abrasion loss only 3.6mg/2000 times.
(Use)
- Use in papermaking, coating .can partly substitute for the expensive titanium dioxide.
- Use in paint, water-based latex paint
- Use as the reinforcing agent in rubber and special cables, as the functional filler of plastic product, ink, food, medicines, cosmetics.
