Viscomixer

Viscosity measurement of coatings is essential at each stage of the manufacturing process to ensure consistent quality standards. Many parameters can affect the rheological behavior of a finished coating resulting in undesirable effects such as inconsistent performance, poor levelling or sagging. The use of high precision measuring instruments is therefore essential in quality control to prevent such problems occurring during formulation, manufacture and application.

The Paintlab+ Viscomixer is a versatile instrument used to measure the change in viscosity during the addition of a solvent or thinner. Three Viscomixer models are available each offering a different measuring range according to the viscosity of the test sample.

A sample from a production batch can be quickly and easily measured in a 250ml tin and the required thinning ratio determined for scaling into the production process. The instrument operates at a fixed speed of 562 rpm to directly measure the viscosity in Poise (P).

Features

top

Precise measurement - High stability motor speed control ensures accuracy and repeatability during each test. Real-time high resolution graphing allows monitoring of changes during measurement providing identification of inconsistencies between samples. Measurement results are displayed instantly on screen after tests.

Advanced temperature monitoring - An integrated temperature probe accurately measures and records sample temperature for each test. As sample viscosity is influenced by test temperature, accurate monitoring and recording ensures reliability of test results.

Automatic operation - Fully automated operation saves time by accurately lowering the rotor into the sample to the correct height. Once the test has completed the rotor automatically raises to drain off, saving time during cleaning. The easy to use quick release magnetic rotor holder allows rapid removal for cleaning after use.

Easy clean design - Lab-tough glass allows easy removal and cleaning of unintentional splashes and smears from the capacitive sense buttons and screen. The solvent resistant anodized aluminium instrument chassis ensures the instrument can be cleaned and restored to pristine condition even in the toughest working environments.

Flexible range configuration - The viscomixer can be configured to use multiple ranges by purchasing additional rotor kits. User selectable ranges with calibration profiles for each rotor.

Calibration - Annual calibration can be performed remotely by the user with the Rhopoint certified recalibration kit. Step by step instructions and automatic verification ensure accurate, traceable results

Test Types

top

Run to stable - Tests for shear thinning or shear thickening to determine the time it takes to reach a constant value. User-defined test time and stability time, result given in Poise at the end of the test.

Run to change - Tests for the modulus point (change in viscosity) in the sample. User defined test time and percentage change, result given in Poise at the end of the test when percentage change is reached

Run to greater than value - Tests for shear thickening. User selectable test time. During this time instrument will look for an increase in reading to target value viscosity reading. This target reading is user selectable. Result is in Poise at the end of the test.

Run to less than value - Tests for shear thinning. User selectable test time. During this time instrument will look for an decrease in reading to target value viscosity reading. This target reading is user selectable. Result is in Poise at the end of the test.

Run to set time - User defined test time, results in Poise at the end of the test.
