With its high degree of thixotropy and yield, Portafill H5 is an effective rheology modifier in aqueous and solvent based formulations. It is ideally suited for different types of adhesives and sealants in place of precipitated alternatives. The unique microfine particle size and the platy morphology provide excellent rheology control, combined with attractive brightness
levels. Adequate surface treatment will result in optimum compatibility with the resin system.
