What Is It About Viscosity?

Water Viscosity

What is Viscosity? Viscosity tells us how thick or thin a liquid is. Viscosity is the property of a fluid that causes it not to flow easily because of the resistance of its molecules. When we use coatings, we need to understand viscosity, because it is key to accurate application, and a finished coated product […]

Why and How Viscosity is Measured

Viscosity Overview Viscosity is a measure of a fluid’s resistance to flow. It describes the internal friction of a moving fluid due to its molecular makeup. A high viscosity (thick) fluid resists motion because of high internal friction, while a low viscosity (thin) fluid flows readily because of low internal friction. Viscosity is measured because […]
