viscosity

The viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of “thickness”: for example, syrup has a higher viscosity than water. With regard to floor finishes, the viscosity of the coating material is central to achieving consistency. It is an effective indicator of concentration of coating solids in the fluid, which is the basis for the thickness and uniformity of the film. Performance parameters all depend on the viscosity of the liquid coating at the point of application.
