The Immobilization Cell for MCR rheometers can be used to perform immobilization measurements on paper coatings.

Immobilization Cell

The Immobilization Cell (IMC) is used to investigate the immobilization kinetics and water retention of paper coatings. The base paper is clamped onto a perforated plate, a pump generates a vacuum. This vacuum extracts the liquid phase of the applied coating while the geometry measures the related change in its rheological behavior. The immobilization cell is patented by Anton Paar.
