Pigmet Volume Concentration (PVC) Coating properties are governed by, among others, the degree of loading of the system with solid particles. Some coatings contain multiple solid particles, while others, like clearcoats, are free of solid particles. The particle loading of a coating is quantified by its Pigment Volume Concentration (PVC). The PVC of a system […]
