Pigment Volume Concentration

PVC (Pigment Volume Concentration)

The ratio of the volume of pigment to the volume of total nonvolatile material present in a coating. The figure is usually expressed as a percentage.

The non-volatile material, the material in the dried film, is represented by pigment and binder.  Solvents and other materials not present in the dried film must not be included in the denominator.

Coatings are usually composed of a mixture of multiple pigments and binders.   In this case, contributions of individual components must be considered.  We multiple components are considered, ideal mixing is assumed (i.e. volumes are additive). 

PVC = volume of pigment / volume total solids = Vp / (Vp + Vb)

 

Vp - volume of pigment

Vb - volume of binder

    The article details how PVC affects the properties of paint, including its color strength, hiding power, and viscosity. It also provides an overview of the various factors that impact PVC, such as the size and shape of the pigment particles and the type of binder used in the paint. Overall, the article is an informative and valuable resource for anyone involved in the paint industry, as it helps to improve the understanding of PVC and its impact on paint formulations.
