Viscosity is an important physical property of liquids that describes how resistant a liquid is to deformation or a change in shape. It indicates how strong the internal friction between the liquid molecules is.

A liquid with a high viscosity flows more slowly than a liquid with a lower viscosity. Examples of liquids with a high viscosity are honey, while water has a low viscosity. Viscosity is usually measured in units such as Pa-s or mPa-s.

In joining technology, viscosity is also used to characterise adhesives. A medium to high viscosity adhesive is easier to use for overhead work than a low viscosity adhesive.
