Detailed Description:
Cas No. :52624-41-6 Composition: Al2O3 •2SiO2
FEATURES AND BENEFITS
Ultrafine and super white calcined kaolin particle with pore on the surface characterized by high brightness, high covering capacity, good light scattering performance, good suspension capacity and easy dispersing performance . It has good dispersing and suspension in oil and water system and can prevent paints from depositing. With chemical inactive performance and anti-react to acid and alkali, it is good to improve paint performance characteristics such as weathering resistance, scrub resistance and abrasion resistance.
