Use the Oil absorption of the pigment and extenders to find out what the minimum of binder is requered for the powders.
Then use the PVC calculation but put in the calculated amount of the binder intstead of the real amount in the formulation.
The outcome of this "PVC calculation is called the CPVC!
Since oil absoption is in weight and in the calculation is in volume: use for binder density : 0.95 kg/dm3.
at last:
When you divide PVC by CPVC you 'll have the PVB.
This value tells something about flexibility and outdoor durability.
The more you come to 1.0 the more you are reaching CPVC.
