Rotational rheometer

A rotational rheometer is a critical instrument in surface engineering used to characterize the rheological properties of materials such as paints, coatings and adhesives.

This device makes it possible to measure the response of a sample to controlled mechanical loads by applying torque and rotational speed to the sample. During the test, the viscosity, elasticity and deformability of the sample are measured, providing important information about its flow behavior and viscoelastic properties.

In surface engineering, the rotational rheometer is often used to evaluate the performance of coatings by examining their flow behavior during the application process and their ability to withstand mechanical stress. By accurately characterizing these rheological properties, manufacturers can improve the quality of their coatings, optimize their applicability in different environments and increase process efficiency.
