ABSTRACT
Urea intercalation compounds were produced in a new designed industrial scale. The conditions and locations of the new industrial process for the production of urea intercalation compound pigment were studied through the control of correlative parameters. Properties of the compound pigment such as particle morphology, particle size distribution and viscosity, were analyzed to evaluate its potentiality for paper coating application. Results showed that the intercalation ratio of urea intercalation compound increased from 6.3% with 2 wt.% of urea addition to 56.08% with 6 wt.% of urea addition. Viscosity concentration of urea intercalation compound improved from 69% of original kaolinite to the highest value, 74.23% of the compound. Particle size distribution was centralized. Properties of light weight papers coated with urea intercalation compound showed interesting results, similar to a standard grade.
