Viscosity

Viscosity is the fluid’s property for resistance to flow or deformation. The higher the viscosity of a product the more it will resist to flow. Using or modifying it is a hot item. Paints are engineered to be non-Newtonian these days and often chemically modified. Additives react to the force that is exerted to the paint, thus making paint almost solid.

Why Should You Measure Viscosity?

Gathering viscosity data on a material gives manufacturers the ability to predict how the material will behave in the real world. For example: if toothpaste does not have the correct viscosity, it can either be too difficult to pump out from the tube, or pump out too much.

Knowing the viscosities of a material also affects how the production and transportation processes are designed.

Viscosity’ is a liquid’s resistance to flow that is measured by time and temperature, and it is paramount to how coating performs on press.

If a coating’s viscosities is too thick, the pumping system won’t be able to pump the liquid from the barrel causing the system to shut down. This will result in no coating being transferred to the sheets.

If the coating is too thin, it will leak from the coating chamber. Since presses run at incredibly high speeds, the thinner liquid will splash all over the press.

Some of the performance issues that can be a result of not measuring your coating’s viscosities include the coating layer being invisible, uneven lay down, and too little coating due to it being watery.
