Flow

The flow time is a key figure that is used to assess the flow behavior of paints. It indicates how long it takes for a certain amount of coating material to flow out of a defined container under specified conditions. This measurement is important in order to characterize the viscosity and workability of the coating material.

To determine the flow time, the coating material is filled into a special flow cup device that provides standardized flow conditions. The time required for the paint to flow through a defined opening of the cup is measured and specified as the flow time. The measurement is usually made in seconds.

The flow time depends on various factors, such as the viscosity of the coating, the composition of the pigments and binders used, the temperature and the coating thickness. A lower value for the flow time indicates a lower viscosity and better flowability of the coating material, while a higher value indicates a higher viscosity and thicker consistency.

The flow time is an important parameter in the coatings industry, as it provides information about the workability and application properties of the coating material. It helps paint manufacturers and users to monitor the consistency of their products and ensure that they meet the specific requirements and standards required for different applications.
