Rheometer
Rheometry is the analytical method used to describe and assess the deformation and flow behavior of materials, i.e. their rheological properties.
Our hybrid rheometers are used in our R&D projects to support material development and formulation of coatings, and to monitor associated curing kinetics. One of the main objectives of our measurements is to evaluate the viscosity of resin formulations as a function of temperature and/or shear stress, in order to ensure compliance with targeted processing and implementation conditions. Rheological analyses also provide key information regarding gel time, pot life, and mix viscosity, which are often critical parameters for proper handling and processing of resin systems. In addition, torsional rheometry enables the characterization of cured materials under torsional loading, providing complementary information to 3-point bending Dynamic Mechanical Analysis (DMA). This approach allows a more representative assessment of viscoelastic behavior under service-like mechanical solicitation, closer to real end-use conditions.
