Sep 25, 2018 · Viscosity is one of the most important properties of coatings (emulsions) that influence their way of deposition and the deposited layer thickness. A wrongly selected viscosity can result in the fact that the layer thickness will be either too small (the coating will not satisfy its task) or too large (which can favor its cracking) [ 25 ].
