| dc.description | The rheological properties of leather finishing formulations were investigated. The rheological analysis was performed in a Ford cup number 4, a Brookfield viscometer, and a rheometer. The effects of the formulation parameters on the viscosity behavior showed similar trends for each technique. The tests in the rheometer showed that soft acrylic resins produced shear thinning formulations, similar to the effect of the finishing pigments. Furthermore, samples containing soft resins and polymeric pigments produced formulations with elastic properties. Finally, the Ford viscosity does not change significantly with the formulation parameters as the Brookfield viscosity does (type of pigment, resin, or resin-pigment ratio). Thus, the non-Newtonian behavior shown by the finishing samples analyzed suggests avoiding the use of the Ford cup when assessing leather finishing formulations. The Brookfield viscometer, however, would provide more reliable viscosity values when a rheometer is not at hand. | |
