Product Description: |
|
JK98 Kaolin is an engineered and structured calcined kaolin featuring ultra high brightness. It has been dehydroxylated by controlled heat treatment for removel of crystalline-bound hydroxy1 group and to improve brightness. JK98 kaolin is highly pulverized for better dispersion. |
