High opacity kaolin pigments and preparation thereof |
摘要 |
An opacifying kaolin clay containing slimes is treated with a low molecular weight crosslinkable cationic polymer to produce a coating clay composition that has high opacification capacity and good rheology without removing the slimes. In the processing the polymer is crosslinked and adheres selectively to the slimes. |
