Viscosity of wet paint at the stage of packaging. It is also defined as delivery viscosity. Packaging viscosity of a paint is determined considering two points:
1) Packaging viscosity should be high enough to prevent settling of fillers, pigments and additives throughout the shelf life of the paint mixture;
2) Packaging viscosity should be low enough to provide homogeneous and easy mixing of the thinner that is added prior to use.
The most suitable viscosity at which paint can be applied by the chosen method with ease.
Measure of resistance of a fluid against flow. The higher the viscosity of a fluid, the more resistance it has to flow.
Accelerated test for predicting the change in the viscosity of an organic coating during storage. For simulating stability during storage, the paint is kept at 50 – 60ºC for a predetermined time.
