Rheology of Coatings: Flow Point Determination with the MCR 92

The flow point is an important rheological parameter that is very suitable for the quality control of coatings. This Application Report provides insight into determining the flow point of coatings by using oscillation measurements with the Anton Paar rotational rheometer, MCR 92.

Introduction

For evaluating the flow behavior of coatings, it is important to find a measurement method that provides a comparison value quickly and accurately. The flow point is a very suitable parameter, which is directly connected to the internal structure of the material. It describes the necessary force that must be expended to make a substance flow. This characteristic value can be determined by using an amplitude sweep in an oscillation measurement. Using the flow point, various samples can be clearly distinguished from each other and evaluated.
