CPVC (Critical Pigment Volume Concentration)
The point where there is just sufficient binder present within a paint to cover each extender particle with a thin layer and fill all voids between particles. CPVC can be calculated from oil absorbtion (OA) as follows:
CPVC = 1/(1+ OAp/K)
where:
- CPVC - Critical Pigment Volume Concentration
- OA - Oil Absorbtion
- p - specific gravity of the pigment
- K - 100 x specific gravity of binder
