Calcined, structured and engineered kaolins As a further processing step, kaolins can be aggregated by either thermal or chemical means. This treatment increases the porosity of the coating layer and hence improves light scattering. The light-scattering coefficient of a coating is a function of both particle and void size, and these two parameters are directly
