Flow Behaviour

Flow behavior is one of the most important characteristics of coating systems in the paper industry. To a great extent, flow behavior determines the handling and application properties as well as the productivity of the process.A key factor in describing flow behavior is viscosity.

For most coating formulations, viscosity is not a constant but depends on various parameters such as temperature or mechanical stress (shear forces). Rheology is the complex interrelationship between viscosity and shear forces.

The rheology of a pigmented system is determined primarily by:

• pigment type

• pigment level

• binder

• additives

• and other chemical/technical parameters such as pH value

In practice, when coating colors are applied, other factors also influence flow behavior:

• paper roughness

• angle and surface of blade

• beam angle, pre-load of blade

Goodrich Agrochem's additives are used to optimize the flow behavior and adjust the formulation for specific application condition & better control of viscosity / rheology.
