    Challenge Solution Your benefit Instrument
    Basic viscosity and rheological measurements

    The paint is too thin or too thick for the application.

    • Analyze the viscosity of the paint.
    • Determine the viscosity at different shear rates for viscosity of paint at rest and during application.
    • Determine the time-dependent behavior at a constant speed/shear rate.
    • Perform quick quality control checks at a constant speed.
    • Know the flow behavior of your paint by determining the viscosity at several speeds or shear rates to adjust the flow behavior at rest or in motion.

    The paint gets stuck while pumping or during application.

    Analyze the yield point of the paint.

    Adjust the formulation of the paint to lower the yield point of the sample so that less force is needed to initiate sample flow.


    The paint produces an inadequate layer thickness or shows sagging after the application.

    Analyze the structural decomposition and recovery of the inner structure of the paint.

    Adjust the formulation of the paint to ensure a sufficiently high wet layer thickness or no sagging.


    The paint is too thick for high-shear application.

    Analyze the viscosity of the paint at high shear rates (1,000 s-1 to 10,000 s-1).

    Ensure properly adjusted viscosity of paint for high-shear applications, e.g. spraying, brushing.


    The paint shows sedimentation on a short time scale.

    Check the sedimentation of particles, e.g. pigments and fillers in your paint.

    Prevent sedimentation of the paint on a short time scale.


    The paint shows phase separation or sedimentation after a certain time at rest.

    Check the storage stability with a frequency sweep and thereby observe and avoid separation of the two phases within the material.

    Prevent phase separation/sedimentation of the paint during long-term storage.


    The paint needs to be applied at various temperature conditions.

    Determine the viscosity exactly at the defined temperature.

    Adjust the paint to its optimum application conditions.


    How long can a two-component material be applied?

    Determine the pot/shelf life.

    Learn when the viscosity is doubled compared to the viscosity at the beginning of the reaction and thus how long a paint can be used when opened.

    Advanced rheological measurements

    The drying/curing behavior of the sample must be adjusted.

    Analyze the drying/curing behavior of the sample with regards to:
    • Physical drying
    • Thermal hardening/curing
    • UV curing
    • Sol-gel time
    • Crosslinking reactions

    Adapt the paint until it reaches the ideal drying or curing behavior.


    The sample does not dry in environments with high humidity.

    Adjust the humidity and temperature of the environment during your measurement.

    Adapt the behavior of the sample to realistic application conditions.


    It has to be defined how long the UV curing sample takes to show a proper crosslinking reactions.

    Simulate your crosslinking reactions under the use of UV light.

    Find the proper formulation for the optimum application result.


    The film is too brittle or soft after curing.

    Determine the DMA behavior of the film.

    Perform fast screening of the dried film behavior.


    Powdery raw materials cannot be pumped.

    Simulate the pumpability of solid raw materials using a powder cell.

    Avoid issues during transport and storage of powdery materials.

    MASTER THE FLOW with our viscometers

    Viscosity measurements of paints and coatings are essential for quality control at every step in the production line. They ensure consistency of incoming raw materials, provide immediate information on the processability and pumpability of a material, and help with verifying the consistency of end products as well as their specifications. A rotational viscometer like ViscoQC 100/300 is commonly used for quality control in the paints industry and fulfills standards such as ISO 2555, ASTM D2196, and many more. Perform a single-point dynamic viscosity determination with ViscoQC 100 for quick coating quality control or start a multi-point viscosity measurement with ViscoQC 300 to determine, for example, the flow behavior and yield point of the paint. Receive outstanding results using an easy-to-use stand-alone instrument with intelligent, valuable features:

    • Ready to use out-of-the-box
    • Built-in digital leveling function to check proper alignment
    • Magnetic coupling for one-hand removal/attachment of spindle
    • Automatic spindle/guard detection and digital instrument alignment check
    • TruMode™ for when spindle/speed combination is unknown
    • Air-counter-cooled Peltier temperature device with T-Ready™ shows when sample has reached temperature equilibration

    The rotational rheometer RheolabQC further enables you to study the structural regeneration of your samples and adapt it properly. With our huge variety of measuring systems available for RheolabQC high shear rates typical for spraying can be simulated. Special Krebs stirrers according to ASTM D562 enable viscosity determination in Krebs units. All measuring systems are automatically recognized by Toolmaster™ to prevent user errors and enhance traceability.

    MASTER THE FLOW with our rheometers

    With a rheometer you can follow the change in your paint’s and coating’s viscosity – from one measuring point to the next. You instantly gain deeper insights into your sample’s deformation, flow behavior, and structure – so you can change matters in your favor right away.

    Enable measurements in both rotational and oscillatory mode. The choice of rheometer depends on the application. To investigate the deformation and flow behavior of a sample consider MCR 72. For observing the samples’ structure, MCR 92 is recommended. For the full range, starting from routine quality control to high-end research and development measurements, the MCR XX2 series is the best choice. The MCR X2 and XX2 series offer application-specific accessories to fully characterize the rheological properties of your paint and coating sample.
