| Résumé : |
Kaolinite is a mineral belonging to the family of aluminosilicates. It is usually referred to as "China Clay" because it was first discovered at Kao-Ling, in China. The term kaolin is generally used fora set of common clay minerals having significant amount of kaolinite.
Of specific commercial interest is the degree of crystallinity of Kaolin that controls the key film property that is brightness, whiteness, opacity, gloss, film strength. Kaolins whiteness and laminar nature makes it extremely suitable for its broad use in coating industry as an extender.
In its hydrous or calcined forms, kaolin is capable of improving the optical, mechanical and rheological properties of a paint. These are widely used in range of PVC paints whether it's glossy, satin or matt paint. They deliver mainly three properties that is increased opacity, whiteness and scrub resistance. In a time when coating manufactures are keen to reduce the TiO2 cost burden, optimization without compromising the performance is a greater challenge, and Kaolin offers an optimum solution.
This paper describes various possibilities and some commercial aspects which Kaolin can create for both TiO2 optimization as well as performance enhancement. |
