WebRheology of disperse systems is an extremely important processing parameter. Being able to characterize and manipulate the flow behavior of dispersions one can ensure their optimal performance. Automotive coatings, for example, should exhibit a distinct low-shear viscosity necessary to provide good leveling but to avoid sagging at the same time. WebWe use both pre-strain and strain amplitude sweep protocols in dynamic rheological measurements where the gel slip was suppressed by the in situ gelation in the cross-hatched parallel plate rheometer geometry. Within the stiffening region, we show the scaling relation for the differential modulus K ∝ σ^1, where σ is stress.
