We have developed a new method to study the dynamics of particle mobility in coating suspensions using the principles of ATR spectroscopy.  Experiments have been performed with paper coating formulations consisting of kaolin and calcium carbonate pigment particles and styrene - butadiene latex binders.  Principles such as binder migration will be presented and are observed dynamically under different drying conditions and conducted under sedimentation and application of external electric fields. In this presentation, we will describe the experimental methods used to measure particle mobility under sedimentation and applied fields and present data and theoretical models for describing the migration of particulates during drying.
