Applications
Ultrafine Kaolin C-98 is specially designed for the coating industry. While imparting opacity to coatings, it can improve gloss, brushability and stability of coating, enabling non-separation of layers after long storage, therefore improving anti-flooding and anti-floating properties. Also, it can enhance film mechanical properties, moist-proof ability as well as impact resistance of the coatings system. Ultrafine Kaolin C-98 plays a role in shielding UV, improving coatings properties like weather fastness, anti-corrosion, heat resistance, acid and alkali resistance, etc.
