Pigment RheoMeter

A pigment rheometer measures the rheological properties of pigments, such as viscosity and elasticity, under shear forces through rotation or oscillation. It is used to evaluate the dispersion stability, application performance, and storage conditions of pigments, and is applied in quality control for the production of coatings and inks.
Selection
When selecting a pigment rheometer, it is essential to consider that the measurement range covers the target pigment viscosity, the fixture material is corrosion-resistant, the temperature control accuracy matches the process requirements, the software functionality supports data export, and the ease of operation is suitable for routine testing environments.
