Extenders

Extender pigments are added in order to reduce the cost of a paint formulation. They are also used to modify the flow (viscosity), sedimentation stability and film strength. Most extenders appear white and possess a refractive index similar to commonly used binders. The majority of them occur naturally and others can be produced synthetically.
