Ultrafine & Superwhite calcined Kaolin |
| Ultrafine
particle size with controlled distribution, very low residue on
325 mesh and low abrasion. High brightness and good light scattering
performance, well-crystallized pseudo-hexagonal kaolinite platelets
in a laminar structure, high covering capacity. Excellent extander
for titanium dioxide.
The paints including MXK101A used as pigment and filler have better
water-keeping capacity, better rheology, lower viscosity and higher
solid slurries. Improve paper performance characteristics, such
as brightness, smoothness, opacity, ink receptivity, coverage
and printability, impart gloss and print gloss. The products have
both advantages of soft kaolin and calcined kaolin.
The paints including MXK101B used as pigment and filler have better
water-keeping capacity, better rheology, and lower viscosity ,
especially in improving brightness and ink receptivity.
Widely used in the manufacture of coated manila, ivory board,
light weight-coating paper, and case coated board and art paper.

Ultrafine & Superwhite calcined Kaolin |
| Ultrafine
particle size with controlled distribution range, very low residue
on 325 mesh and easy to disperse, good rheology, suspension, and
stability, premium brightness, high degree of light scattering
and high covering capacities, excellent extender for titanium
dioxide. It can improve many characteristics of paint and coating
such as scrubbability, burnish resistance, climate resistance,
stable property of storage etc, absolutely necessarily for making-up
low VOC and high solid content paints. Widely used in latex paint,
powder coatings, high quality paint.
