Coatings, Paints | ViscoQC™ Quality Control of Coatings and Paints
Analyzing the viscosity of paints at different speeds shows you how the paint behaves during e.g. painting the wall. This application report can offer you a brief insight on typical measurements with the rotational viscometer ViscoQC™ 100.
A rotational viscometer like the ViscoQC™ 100 is commonly used for quality control of coatings and paints. The viscosity (“thickness”) of the paint specifies whether the paint can be applied with a brush, a roller, a sprayer, or other methods. Furthermore, paint needs to be applied uniformly to the surface without uneven ridges. Quick single point viscosity checks at one or at different speeds to study the shear thinning behavior of paints and coatings are possible with ViscoQC™ 100. Shear thinning means that the viscosity decreases by increasing the speed.
- Instrument: ViscoQC™ 100 - R
- Spindle: RH5
- Guard: R
- Speeds: 2 rpm, 20 rpm, 40 rpm
- Temperature: 23 °C
- Sample: Synthetic dispersion paint
All measurements were performed with ViscoQC™ 100 - R rotational viscometer from Anton Paar GmbH according to ASTM D2196-10. ViscoQC™ 100 - R is suited for a viscosity range of 10 to 40 000 000 mPa·s.
ASTM D2196-10 is a standard test method for the investigation of the rheological properties of non-Newtonian materials such as paints and coatings by a rotational (spindle-type) viscometer.
