ABSTRACT:
In a proposed method for determining the immobilization of a colloidal coating dispersion which is applied to a porous substrate, the colloidal coating dispersion is applied to the porous substrate which forms a bounding surface of the measuring gap of a rheometer, and the change in the viscosity as a function of time is measured. The method is particularly suitable for measuring the immobilization of a paper coating slip on base paper.
