The business objective is to manufacture an economically viable chemically structured clay to replace thermally structured calcined clay. The technology will provide substantial benefit in paper coating. The structured pigment containing 90% clay and 10% TiO2 vs the loose blend of these materials as a filler for paper was evaluated. A plan to improve the permanence of the structured pigment using dual functional dispersed pigments is in place. The cationic dispersant for TiO2 will also be a binder. Spray drying will be use to fix the structure of the internally bound structured pigment
